Description

この発明は、楽曲の音階・コード・和音の移調情報を表示する移調装置に関する。   The present invention relates to a transposing device that displays transposition information of a musical scale, chord, and chord.

従来の移調装置は楽曲の音階・コード・和音を任意の設定値だけずらせた移調後の音階・コード・和音と対応させて表示する特許文献１のような装置があった。
実開 平３−８９４６８この移調装置を用いることでアマチュアなどの初心者でも簡単に任意の移調を行うことができるものであった。 As a conventional transposing apparatus, there is an apparatus such as Patent Document 1 that displays a musical scale, chord, and chord in correspondence with a scale, chord, and chord after transposition by shifting an arbitrary set value.
3-89468 By using this transposing device, even a beginner such as an amateur can easily perform arbitrary transposition.

しかしながら特許文献１の実施形態においては任意の移調を簡単に行うことはできても、どれだけ移調すれば初心者に演奏しやすい音階・コード・和音に変換されるかは移調を行ってみないと分からなかった。一般的な１２音階の場合移調は11通りあり、11通りの中から最適な移調を選ぶには、11回の移調作業を繰り返し行う必要があるため時間がかかり不便であった。例として下記の楽曲のギター伴奏を行う場合の移調作業を例示する。
楽曲例１ Ｅ (Ｃ＃ｍ) Ｂ７ (Ｇ＃ｍ) Ａ
この楽曲例１を順次移調した移調楽曲例１−１１を下記に示す。
移調例１ Ｆ Ｄｍ Ｃ７ Ａｍ (Ａ＃)
移調例２ (Ｆ＃) (Ｄ＃ｍ) (Ｃ＃７) (Ａ＃ｍ) (Ｂ)
移調例３ Ｇ Ｅｍ Ｄ７ (Ｂｍ) Ｃ
移調例４ (Ｇ＃) (Ｆｍ) (Ｄ＃７) (Ｃｍ) (Ｃ＃)
移調例５ Ａ (Ｆ＃ｍ) Ｅ７ (Ｃ＃ｍ) Ｄ
移調例６ (Ａ＃) (Ｇｍ) Ｆ７ Ｄｍ (Ｄ＃)
移調例７ Ｂ (Ｇ＃ｍ) (Ｆ＃７) (Ｄ＃ｍ) Ｅ
移調例８ Ｃ Ａｍ Ｇ７ Ｅｍ Ｆ
移調例９ (Ｃ＃) (Ａ＃ｍ) (Ｇ＃７) (Ｆｍ) (Ｆ＃)
移調例１０ Ｄ (Ｂｍ) Ａ７ (Ｆ＃ｍ) Ｇ
移調例１１ (Ｄ＃) (Ｃｍ) (Ａ＃７) (Ｇｍ) (Ｇ＃)
これらの記号のうち、括弧のついている音階・コード・和音はギター初心者には演奏しずらいものである。ここでＡからＧ＃までは１2の音階を示し、無印（メジャー）、ｍ（マイナー）、７（セブン）はコード・和音の種別を表す。 However, in the embodiment of Patent Document 1, although arbitrary transposition can be easily performed, it is necessary to transpose how much the transposition is converted into a scale, chord, or chord that is easy to play for beginners. did not understand. In the case of a general 12-tone scale, there are 11 transpositions, and selecting the optimal transposition out of 11 ways is time consuming and inconvenient because it is necessary to repeat 11 transposition operations. As an example, the transposition work when performing the guitar accompaniment of the following music is illustrated.
Example 1 E (C # m) B7 (G # m) A
A transposed music example 1-11 obtained by sequentially transposing this music example 1 is shown below.
Transposition example 1 FDm C7 Am (A #)
Transposition example 2 (F #) (D # m) (C # 7) (A # m) (B)
Transposition Example 3 G Em D7 (Bm) C
Transposition Example 4 (G #) (Fm) (D # 7) (Cm) (C #)
Transposition Example 5 A (F # m) E7 (C # m) D
Transposition Example 6 (A #) (Gm) F7 Dm (D #)
Transposition Example 7 B (G # m) (F # 7) (D # m) E
Transposition Example 8 C Am G7 Em F
Transposition Example 9 (C #) (A # m) (G # 7) (Fm) (F #)
Transposition Example 10 D (Bm) A7 (F # m) G
Transposition Example 11 (D #) (Cm) (A # 7) (Gm) (G #)
Of these symbols, bracketed scales, chords and chords are difficult for beginner guitar players. Here, A to G # indicate 12 scales, and no mark (major), m (minor), and 7 (seven) indicate chord / chord types.

この1１例の中で初心者がギターで伴奏できる移調楽曲は移調例８のみである。（すべての音階・コード・和音に括弧が付いていない）すなわち初心者は移調例８のように音階・コード・和音を移調することで、この楽曲例１を伴奏することができる。この例では8回、最悪11回移調作業を行わないと最適な移調が見つからず、演奏できる移調を行うまでに時間がかかることが分かる。そこで本発明は初心者が演奏できる移調を簡単に行えるようにすることを課題とする。   Of these 11 examples, the only transposition music that a beginner can accompany with a guitar is transposition example 8. (All scales, chords, and chords are not parenthesized.) That is, a beginner can accompany this musical example 1 by transposing scales, chords, and chords as in transposition example 8. In this example, unless the transposition work is performed 8 times or the worst 11 times, the optimum transposition cannot be found, and it can be seen that it takes time to perform transposition that can be performed. Therefore, an object of the present invention is to make it easy to perform transposition that can be performed by a beginner.

以上の課題を解決するために、第一発明は、楽曲で使用されている音階・コード・和音を表示する第１の表示手段と、前記音階・コード・和音を任意の音階だけ移調する移調手段と、移調後の楽曲の音階・コード・和音を表示する第２の表示手段と、移調後の楽曲の音階・コード・和音の演奏難易度を表示する手段を設けたことを特徴とする移調装置である。   In order to solve the above problems, the first invention includes a first display means for displaying a scale, chord, and chord used in a musical composition, and a transposition means for transposing the scale, chord, and chord by an arbitrary scale. And a second display means for displaying the scale, chord and chord of the music after transposition, and a means for displaying the performance difficulty of the scale, chord and chord of the music after transposition. It is.

また第二発明は、第一発明において演奏難易度を各音階ごとに、それぞれ複数のコード・和音種別ごとに設けた事を特徴とする移調装置である。   The second invention is a transposition device characterized in that, in the first invention, the performance difficulty level is provided for each scale and for each of a plurality of chords and chord types.

第一発明、第二発明によれば初心者が演奏できる移調を簡単に行えるようにすることがきる。   According to the first invention and the second invention, it is possible to easily perform a transposition that a beginner can perform.

この発明の実施例について図面を用いて説明する。図１は第１の実施例の正面図である。難易度表示体１は移調後の音階とその音階ごとのコード・和音の演奏の難易度を色分けして表示している。図２に難易度表示体１の正面図を示す。ここで示す色分けは初心者の演奏のし易さに応じて行ってある。青は演奏できる事を示し、赤は演奏できない事を示す。演奏者の得て不得手に応じてカスタマイズしても良い。２は演奏する楽曲に使用されている音階・コード・和音を表示する可動体である。図３にその正面図を示す。使用される音階・コード・和音に対応する部分の窓３を開閉することで使用、不使用を表示する。ここでは使用する音階・コード・和音に対応する窓を開にする。この窓は厚紙等を材料とした可動体２の対応部分にコの字形の切り込みを入れ折り曲げることで実現できる。この難易度表示体１と可動体２は重ね合わせて音階方向に自在に可動するよう構成され、各音階のコード・和音の種別ごとに重なり合い、窓を開にすると対応する各音階のコード・和音の演奏の難易度を表す色が見える位置関係にある。図１は可動体２の窓を楽曲例１で使用するコード・和音に対応させて開にした状態で、移調していない状態を表している。実施例１を使用して楽曲例１を初心者の演奏可能な移調例８に移調する手順を詳細に説明する。   Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of the first embodiment. The difficulty level display 1 displays the scale after transposition and the difficulty of playing chords and chords for each scale in different colors. FIG. 2 shows a front view of the difficulty level display body 1. The color coding shown here is performed according to the ease of performance for beginners. Blue indicates that it can be played, and red indicates that it cannot be played. It may be customized according to the performance of the performer. Reference numeral 2 denotes a movable body that displays the scale, chord, and chord used in the musical piece to be played. FIG. 3 shows a front view thereof. Use and non-use are displayed by opening and closing the window 3 corresponding to the scale, chord and chord used. Here, the windows corresponding to the scales, chords and chords to be used are opened. This window can be realized by making a U-shaped cut into a corresponding part of the movable body 2 made of cardboard or the like and bending it. The difficulty level display body 1 and the movable body 2 are configured to overlap each other and move freely in the scale direction, overlap each type of chord / chord of each scale, and open the window, the corresponding chord / chord of each scale. There is a positional relationship where the color representing the difficulty level of the performance can be seen. FIG. 1 shows a state in which the window of the movable body 2 is opened in correspondence with the chords and chords used in the music example 1 and is not transposed. A procedure for transposing the musical example 1 to the transposing example 8 that can be performed by a beginner using the first embodiment will be described in detail.

楽曲例１の最初のコード・和音 Ｅ に対応する可動体の窓を開にする。すなわち、音階 Ｅ の横線とコード種別 メジャー の縦線の交わる位置の窓を折り曲げて下の難易度表示体１が見えるようにする。同様に２から５番目のコード・和音に対応する窓を開にする。
可動体２を難易度表示体１の一番下に合わせ、窓から見える色を確認する。（図１の状態）赤い色が２ケ見えている。赤い色が一つでも見えれば演奏できないので、可動体２を一つ分上に移動させ同様に色を確認しすべて青色になるまで順次移動させる。8回移動させた時すべての窓の色が青になる。この状態を図４に示す。図４の位置に移動した可動体２と難易度表示体１を使用して移調作業を行う。楽曲例１の最初のコード Ｅ に対応する可動体２の Ｅ の音階の横線をたどり、矢印の先にある移調後の音階を見る。そこに Ｃ の音階があり Ｅ がメジャーコードであるので Ｃ に書き換える。同様に２から5番目までのコード・和音を書き換えて移調作業終了する。移調後のコード・和音には初心者が演奏できないコード・和音がないので初心者でも演奏可能となる。実施例１では移動体を直線的に可動させたが、回転体としても同様の構成が可能である。 The window of the movable body corresponding to the first chord / chord E of sample music 1 is opened. That is, the lower difficulty indicator 1 is made visible by folding the window at the position where the horizontal line of the scale E intersects the vertical line of the chord type major. Similarly, the windows corresponding to the 2nd to 5th chords and chords are opened.
Move the movable body 2 to the bottom of the difficulty level display body 1 and check the color visible from the window. (State in FIG. 1) Two red colors are visible. Since even one red color can be seen, it cannot be played, so the movable body 2 is moved up by one and the color is confirmed in the same manner until all the colors become blue. All windows turn blue when moved 8 times. This state is shown in FIG. Transposition work is performed using the movable body 2 and the difficulty level display body 1 moved to the position of FIG. Follow the horizontal line of the scale of E of the movable body 2 corresponding to the first chord E of the example 1 and see the scale after transposition at the end of the arrow. There is a scale of C there, and E is a major chord, so it is rewritten as C. In the same way, transposing work is completed after rewriting the second to fifth chords and chords. Since the transposed chords and chords have no chords or chords that beginners cannot play, even beginners can play. In the first embodiment, the moving body is moved linearly, but the same configuration is possible as a rotating body.

次に実施例２について図面を用いて説明する。図５は第２の実施例の正面図である。本体１１と回転体１２は中心をハトメ１３で回転自在に止められている。クリップ１４から１８は本体１１の楽曲で使用する音階に対応したクリップ装着場所に装着されている。必要に応じてその数を増減する。クリップは2種類に色分けされており、１４，１５，１６は青いクリップでメジャー、セブンコード・和音に対応し、１７，１８は赤いクリップでマイナーコード・和音に対応している。１１の本体は演奏する楽曲で使用する音階・コード・和音のクリップ装着場所にクリップを装着することで表示する。回転体１２は移調後の音階・コード・和音を表示し、また初心者の演奏し易さに応じて色分けしてある。青色はメジャー、セブンコード・和音、が演奏し易いことを表し、赤色はマイナーコード・和音が演奏し易いことを表している。図５の回転体１２の色分けはＡ，Ｄ，Ｅのマイナーコード・和音が演奏し易く、赤色に色付けされ、Ａ，Ｃ，Ｄ，Ｅ，Ｆ，Ｇのメジャー、セブンコード・和音が演奏し易く青色に色付けされている。実施例２を使用して楽曲例１を初心者に演奏し易い移調例８に移調する手順を詳細に説明する。   Next, Example 2 will be described with reference to the drawings. FIG. 5 is a front view of the second embodiment. The main body 11 and the rotating body 12 are rotatably stopped by a grommet 13 at the center. Clips 14 to 18 are mounted at clip mounting locations corresponding to the scale used in the music of the main body 11. Increase or decrease the number as needed. The clips are color-coded into two types: 14, 15 and 16 are blue clips corresponding to major, seven chords and chords, and 17 and 18 are red clips corresponding to minor chords and chords. The main body of 11 is displayed by attaching a clip to the clip attachment location of the scale, chord and chord used in the music to be played. The rotating body 12 displays the scale, chord, and chord after transposition, and is color-coded according to the ease of performance for beginners. Blue indicates that major and seven chords and chords are easy to play, and red indicates that minor chords and chords are easy to play. The color coding of the rotating body 12 in FIG. 5 is easy to play A, D, E minor chords and chords, and is colored red, major A, C, D, E, F, G major, seven chords and chords are played. Easily colored blue. A procedure for transposing music example 1 to transposition example 8 that is easy for beginners to perform using Example 2 will be described in detail.

楽曲例１の最初のコード・和音 Ｅ に対応する本体１１のＥのクリップ装着場所にメジャーコードの種別を表す青色のクリップを取り付ける。同様に２から５番目の音階・コード・和音に対応するクリップを取り付ける。回転体の音階と本体の音階が同じになるよう回転体を回転させて合わせる。（図５の状態）クリップの色とそのクリップの装着された音階の矢印の先の回転体の音階の着色された色にクリップの色と同じ色があるかを確認する。一つでもクリップの色が回転体の対応する音階の枠に見えなければ演奏できないので、回転体１２を一つ分右に回転させ同様に色を確認しすべて同じ色があるまで順次回転させる。8コマ分回転させた時すべて同じ色があることが確認できた。この状態を図６に示す。図６の状態で移調作業を行う。楽曲例１の最初のコード Ｅ に対応する本体１１の Ｅ の音階の矢印の先にある移調後の音階を見る。そこに Ｃ の音階があり Ｅ がメジャーコードであるので Ｃ に書き換える。同様に２から5番目までのコード・和音を書き換えて移調作業終了する。移調後のコード・和音には初心者が演奏できないコード・和音がないので初心者でも演奏可能となる。実施例２ではコード・和音の種類を2種類に集約したが、実施例１のごとく3種類でも可能であり、マイナーコードのみの一種類でも簡易的には可能である。またクリップにより使用するコード・和音を表示したが本体１１を厚紙等で構成し切り込みを入れ、折り返すことで表示するなどの方法でも良い。   A blue clip representing the type of the major chord is attached to the E clip mounting location of the main body 11 corresponding to the first chord / chord E of the example 1 of music. Similarly, clips corresponding to the second to fifth scales, chords and chords are attached. Rotate the rotating body so that the scale of the rotating body and the scale of the main body are the same. (State in FIG. 5) It is confirmed whether the color of the clip and the colored color of the scale of the rotary body at the tip of the musical scale arrow to which the clip is attached have the same color as the clip. Since even one clip cannot be played unless the color of the clip can be seen in the frame of the corresponding scale of the rotator, the rotator 12 is rotated to the right by one turn and the colors are similarly checked until all the same colors are present. It was confirmed that all the same colors were obtained when rotated by 8 frames. This state is shown in FIG. Transposition work is performed in the state of FIG. The scale after the transposition at the end of the arrow of the scale E of the main body 11 corresponding to the first chord E of the music example 1 is seen. There is a scale of C there, and E is a major chord, so it is rewritten as C. In the same way, transposing work is completed after rewriting the second to fifth chords and chords. Since the transposed chords and chords have no chords or chords that beginners cannot play, even beginners can play. In the second embodiment, the types of chords and chords are consolidated into two types. However, as in the first embodiment, three types are possible, and only one type of minor chord can be simplified. In addition, the chords and chords used by the clip are displayed, but the main body 11 may be made of cardboard or the like, and may be displayed by cutting and turning.

続いて実施例３について図面を用いて説明する。図７はパーソナルコンピューター等の入力手段、処理手段、表示手段を含む装置で動作するプログラムのフローチャートである。本フローチャートを用いて、楽曲例１を初心者の演奏し易い順に移調コードをオリジナルコードと対応させて表示する手順をＳＴＰ１から順を追って詳細に説明する。
ＳＴＥＰ１．初心者がギターのコード・和音を演奏する場合の一般的な難易度を事前に設定しておく。この設定した音階、コード・和音種別ごとの難易度表の表示例を図８に示す。ここで難易度１は演奏し易い事を、難易度２は演奏し難い事を、難易度３は演奏できない事を示す。たとえばＢの音階であれば、コード・和音の種別ごとにそれぞれB（メジャー）は３なので演奏できない事を示し、Ｂｍ（マイナー）は２なので演奏し難い事を示し、Ｂ７（セブン）は演奏し易い事を示す。この難易度を演奏者それぞれに合わせてカスタマイズする場合はここで難易度を修正する。
ＳＴＥＰ２．オリジナルの楽曲（移調前の楽曲）で使用している音階・コード・和音（オリジナルコード）を順次入力する。ここでは楽曲例１のＥ，Ｃ＃ｍ，Ｂ７，Ｇ＃ｍ，Ａを順次入力する。
ＳＴＥＰ３．オリジナルコードの難易度を図８の難易度表示画面の数値を用いて計算する。まず難易度３のコード・和音の個数を計算する。ここではC#mとG#mのみなので２とする。次に難易度２のコード・和音の個数を計算する。この個数を小数点以下の数として難易度３の個数の小数点以下に加える。ここでは２の難易度のコード・和音は無く０ケなので２．０となる。
ＳＴＥＰ４．オリジナルコードからそれぞれのコード・和音を半音づつ高めた＋１コードを作成する。ここではＦ、Ｄｍ、Ｃ７、Ａｍ、Ａ＃となる。＋１移調コードの難易度を計算する。まず難易度３のコード・和音の個数を計算する。ここではＡ#のみなので１とする。次に難易度２のコード・和音の個数を計算する。この個数を小数点以下の数として難易度３の個数の小数点以下に加える。ここでは２の難易度のコード・和音は無く０ケなので１．０となる。
ＳＴＥＰ５−１４．ＳＴＥＰ４と同様に＋２から＋１１までの移調コードを作成し、同様に難易度を計算する。
ＳＴＥＰ１５．ＳＴＥＰ２で入力されたオリジナルコードとＳＴＥＰ３で計算された難易度を最初に表示し、次にＳＴＥＰ４からＳＴＥＰ１４で作成、計算された移調コード、難易度を、難易度の易しい（ここでは数値の低い順）移調コードから順番にオリジナルコードと関連付けて表示する。この表示例を図９に示す。この表示例からオリジナルコードのＥをＣに、Ｃ＃ｍをＡｍに、Ｂ７をＧ７に、Ｇ＃ｍをEmに、ＡをＦにそれぞれ移調する事で初心者でも演奏できる移調コードに変換された。さらに移調度数も参考に表示してある。 Next, Example 3 will be described with reference to the drawings. FIG. 7 is a flowchart of a program that operates in an apparatus including an input means such as a personal computer, processing means, and display means. Using this flowchart, the procedure for displaying the transposition code in correspondence with the original code in the order in which it is easy for a beginner to perform the music example 1 will be described in detail step by step from STP1.
STEP1. Set the general difficulty level for beginners playing guitar chords and chords in advance. FIG. 8 shows a display example of the difficulty level table for each set scale and chord / chord type. Here, difficulty level 1 indicates that performance is easy, difficulty level 2 indicates that performance is difficult, and difficulty level 3 indicates that performance is not possible. For example, for the scale of B, each chord / chord type indicates that B (major) is 3, so it cannot be played, Bm (minor) is 2, so it is difficult to play, and B7 (seven) plays. Indicates that it is easy. When customizing this difficulty level according to each performer, the difficulty level is corrected here.
STEP2. The scale, chord, and chord (original chord) used in the original music (the music before transposition) are entered in sequence. Here, E, C # m, B7, G # m, and A of Musical Example 1 are sequentially input.
STEP3. The difficulty level of the original code is calculated using the numerical value on the difficulty level display screen of FIG. First, calculate the number of chords and chords with difficulty level 3. Here, since only C # m and G # m, it is set to 2. Next, the number of chords and chords with difficulty level 2 is calculated. This number is added as a number after the decimal point to the number of difficulty level three. Here, there are no chords and chords with a difficulty level of 2 and 0, so it is 2.0.
STEP4. Create a +1 chord from the original chord by raising each chord / chord in semitones. Here, F, Dm, C7, Am, and A #. Calculate the difficulty of the +1 transpose code. First, calculate the number of chords and chords with difficulty level 3. Here, only A # is set to 1. Next, the number of chords and chords with difficulty level 2 is calculated. This number is added as a number after the decimal point to the number of difficulty level three. Here, there are no chords and chords with a difficulty level of 2 and 0, so it is 1.0.
STEP5-14. Similarly to STEP 4, transpose codes from +2 to +11 are created, and the difficulty level is calculated in the same manner.
STEP15. The original code input in STEP 2 and the difficulty level calculated in STEP 3 are displayed first, and then the transposition codes and difficulty levels created and calculated in STEP 4 to STEP 14 are displayed in order of difficulty (in this case, in ascending order of numerical values). ) Display in association with the original code in order from the transposition code. An example of this display is shown in FIG. From this display example, the original chord E is converted to C, C # m to Am, B7 to G7, G # m to Em, and A to F. . The transposition frequency is also displayed for reference.
