Description

Percussion Instrument The present invention relates to percussion instruments, preferably tuned percussion instruments comprising an acoustic pickup. The present invention also relates to methods of making such percussion instruments.
Tuned percussion musical instruments are known. Such instruments include steelpans considered as a traditional art form in Trinidad and Tobago. The steelpan has playing areas of definite pitch, on one or more continuous metal note bearing surfaces. Steelpans are disclosed in US-A-2011/62510.
A development of the steelpan is the hang (also known as a handpan), originally conceived by PANArt Hangbau AG and since developed by a number of other makers.
Handpans in their basic form are a metal hollow shell of two segments fixed together with a tuned centre tone field of definite pitch surrounded by a number of other tone fields. A sound hole is present in the shell.
Handpans are disclosed in CH-A-693 319 and US design patents 794 115, 777 245, 766 356, 759 747, 737 370.
The sound of percussion instruments such as handpans is characteristic and becoming more popular. However, it has proven difficult to successfully amplify handpans, especially for performances outside of the studio. Attempts have been made to amplify by directing external microphones at the instrument and by attaching microphones (e.g. with tape) to the surface of the shell. Unfortunately, such attempts tend to introduce distortion and are prone to feedback, especially when there are ambient sounds or there is electromagnetic interference during a performance.
There is, therefore, a need for improved amplification of percussion instruments such as handpans. It is an aim of the present invention to address this need.
The present invention accordingly provides, in a first aspect, a percussion instrument comprising, a hollow shell, the hollow shell comprising an upper segment having an upper segment rim and a lower segment having a lower segment rim, a spacer between the upper segment rim and the lower segment rim, and an acoustic pickup located between the upper segment rim and the lower segment rim and between the spacer and the interior of the hollow shell.
The hollow shell will usually comprise ferrous metal, preferably steel. The metal may be treated or coated e.g. steel may be nitrided. The steel may be stainless steel.
Generally, the spacer may comprise a spacer ring extending around the rim.
The spacer advantageously comprises a non-ferrous metal, preferably brass. Such metals are advantageous because they have surprisingly been found by the inventor to provide good properties and tone.
It is preferred that the acoustic pickup is an elongate pickup, extending at least partially around the rim. The elongate pickup may extend only partially around the rim, but usually will extend substantially wholly around the rim.
In preferred embodiments, the acoustic pickup comprises a piezoelectric pickup, and is preferably a piezoelectric cable pickup. Thus, in the preferred embodiments, the piezoelectric cable may extend at least partly (but preferably substantially wholly) around the rim.
The lower segment rim (and/or upper segment rim) may comprise a flange and, preferably, the spacer may be of narrower width than the flange. If the spacer is then located on the distal part of the flange, it allows the acoustic pickup to be conveniently located on the proximal part of the flange.
Preferably, therefore, the spacer is a ring spacer with an outer diameter substantially the same as the outer diameter of the upper segment rim and flange and/or substantially the same as the outer diameter of the lower segment rim and flange. Furthermore, preferably, the spacer is a ring spacer with an inner diameter greater than the internal diameter of the upper segment rim and flange and/or greater than the internal diameter of the lower segment rim and flange.
Preferably the spacer may be a ring spacer with a width less than the width of the flange, allowing the acoustic pickup to be located on the proximal part of the flange, adjacent the spacer.
It is preferred that the acoustic pickup is held under pressure between the upper segment rim and lower segment rim. This is advantageous because pressure on, for example, a piezoelectric pickup has been surprisingly found to improve acoustic performance and especially amplification.
In some embodiments, the depth of the spacer is preferably less than diameter of the acoustic pickup (i.e. there is a "pinch"). This enables the acoustic pickup to be held in place with pressure applied by the upper and lower segment rims (and/or flanges) when in position against the, shallower, spacer.
The depth of the spacer (i.e. thickness of the material of the spacer) may be in the range 1.0 to 2.0 mm, preferably 1.1 mm to 1.9 mm, more preferably 1.3 mm to 1.7 mm, most preferably around 1.5 mm.
The diameter of the acoustic pickup may be in the range 1.1 to 2.5 mm, preferably 1.2 mm to 2.0 mm, more preferably, 1.4 mm to 1.8 mm, most preferably around 1.6 mm.
The difference between the depth of the spacer (i.e. thickness of the material of the spacer) and the diameter of the acoustic pickup is preferably in the range -0.5 mm to +0.5 mm. Preferably, the difference between the depth of the spacer and the diameter of the acoustic pickup is in the range -0.2 mm to +0.4 mm, more preferably -0.1 mm to +0.3 mm, most preferably 0 mm to +0.2 mm.
The difference between the depth of the spacer and the diameter of the acoustic pickup affects the sound and amplification of the percussion instrument. Generally, where the difference is below -0.5 mm (i.e. the diameter of the acoustic pickup is 0.5 mm or greater than the depth of the spacer), the sound is good but amplification is generally less.
Where the difference is above about 0.5 mm, the amplification is good but the quality of sound may suffer.
For convenient connection to an amplifier, the percussion instrument may further comprise an output jack installed in the hollow shell. Usually, the output jack will be (electrically i.e. functionally) connected to the acoustic pickup.
The acoustic pickup may be fixed using adhesive, and the hollow shell may be formed by fixing the upper segment rim, the spacer and the lower segment rim with adhesive. Thus, the instrument may further comprise at least one adhesive bead between the upper segment rim and lower segment rim. The adhesive bead may comprise silyl modified polymer (SMP) adhesive.
Percussion instruments of the present invention may comprise a number of tone fields of definite pitch. Thus, it is preferred that the hollow shell comprises a plurality of tuned tone fields (which may also be known as playing areas).
To provide good acoustic properties, the instrument may further comprise a sound hole in the hollow shell. The sound hole may be in the upper segment but is preferably in the lower segment.
The hollow shell may be of diameter in the range 16 inch (40 cm) to 24 inch (61 cm). Usually, the hollow shell may be of a diameter of 18 inch (45 to 46 cm) or 21 inch (53 to 54 cm).
The preferred acoustic range of the percussion instrument is in the range E2 to C7, preferably B2 to G5.
The percussion instrument may be tuned to play a notes in a musical scale selected from C# minor, D minor, E minor, E major, F minor, G major, G# minor, A and B minor.
Thus, the percussion instrument may be tuned to one of the following scales: C# Annaziska (with tone fields tuned to the notes G# A B C# D# E F# G#), C# Mystic 7 (with tone fields tuned to the notes G# A C# D# E G# B), C# Raga Desh (with tone fields tuned to the notes G# B C# F F# G# B C#), C# Ysha Savita (with tone fields tuned to the notes G# C C# D# F F# G# C#), D Integral (with tone fields tuned to the notes A Bb C D E F A), D Kurd 8 (with tone fields tuned to the notes A Bb C D E F G A), D Kurd 9 (with tone fields tuned to the notes A Bb C D E F G A (C5 Bottom Note)), D Celtic Minor (with tone fields tuned to the notes A C D E F G A), D Celtic 8 (with tone fields, for example being tuned to the notes A C D E F G A C), E Kurd 8 (with tone fields tuned to the notes BCDE F# G A B), E Kurd 9 (with tone fields tuned to the notes BCDE F# G A B D), E SaBye (with tone fields tuned to the notes A B C# D# E F# G# B), F Integral (with tone fields tuned to the notes C Db Eb F G Ab C), F Integral 8 (with tone fields tuned to the notes C Db Eb F G Ab C Eb), F Low Pygmy (with tone fields tuned to the notes G Ab C D# P G Ab C), or G Oxalista (with tone fields tuned to the notes BCDEG ABC D).
Other scales to which the percussion instruments may be tuned are, for example: G GiZa (with tone fields tuned to the notes Bb D Eb F# G A Bb D), G# Kurd 9 (with tone fields tuned to the notes D# E F# G# A# B C# D# F#), A Oxalis (with tone fields tuned to the notes C# D E F# A C# D E), or B Minor (with tone fields tuned to the notes D E F# G A B C# D).
As discussed above, piezoelectric pickups are advantageous and produce excellent quality sound.
Thus, in a second aspect, the present invention provides a percussion instrument comprising a hollow shell having an upper segment and a lower segment, and a piezoelectric acoustic pickup installed inside the hollow shell.
An output jack installed in the hollow shell is greatly advantageous.
Accordingly, in a third aspect, the present invention provides a percussion instrument comprising a hollow shell having an upper segment and a lower segment, an acoustic pickup installed inside the hollow shell and an output jack fixed in the hollow shell and connected to the acoustic pickup.
The invention provides a percussion instrument with an acoustic pickup that may be manufactured in an efficient manner.
In a fourth aspect, the present invention accordingly provides a method of making a percussion instrument comprising a hollow shell, the method comprising: providing an upper segment having an upper segment rim, providing a lower segment having a lower segment rim, providing a spacer and placing the spacer between the upper segment rim and the lower segment rim, installing an acoustic pickup between the upper segment rim and the lower segment rim and between the spacer and the interior of the hollow shell, and joining the upper segment and lower segment thereby forming a hollow shell.
The percussion instrument of all aspects of the present invention is most preferably a handpan.
Preferred and optional aspects of the second, third and fourth aspect of the invention are as set out above in relation to the first aspect.
An embodiment of the present invention will now be described with reference to the following figures, in which: Figure 1 shows a schematic, partially exploded side view of a percussion instrument of the present invention.
Figure 2 shows the inner surface of the lower segment of the shell of the percussion instrument of Figure 1.
Figure 3 is a schematic section through part of the rim of the percussion instrument of Figure 1.
Figure 1 shows a schematic, partially exploded view of percussion instrument of the invention in the form of a handpan 2. The handpan 2 is formed of a steel hollow shell with an upper segment 4 and a lower segment 6 and a brass spacer ring 18 between the steel upper segment 4 and steel lower segment 6. At the crown of the upper segment 4 is the crown tone field 3 tuned to a definite pitch. Around the upper segment 4 are upper tone fields 12 each also tuned to a definite pitch. On the lower segment 6 there are lower tone fields 14 each also tuned to a definite pitch. The tone fields 3, 12, 14 together are tuned to the notes in a musical scale enabling the performance of melodies. A sound hole 16 is formed at the base of the lower segment 6.
At the widest, lower part of the upper segment 4 is the upper segment rim 11 with an upper segment flange 10 extending outwardly. Similarly, at the widest, upper part of the lower segment 6 is the lower segment rim 9 with a lower segment flange 8 extending outwardly.
When assembled, the spacer ring 18 is located between the upper segment 4 and lower segment 6 extending around the upper segment flange 10 and lower segment flange 8. The spacer ring 18 has an outer diameter substantially the same as that of the upper segment flange 10 and lower segment flange 8 so that the outer surface of the hollow shell is substantially flush around the equator. The spacer ring 18 is less wide than the upper segment flange 10 and lower segment flange 8. An elongate piezoelectric cable pickup 20 extends around the lower segment 4 located on the interior part of the flanges 8, 10 between the spacer ring 18 and the interior of the hollow shell. The spacer ring 18 is shallower in depth (at about 1.5 mm) than the diameter of the piezoelectric cable pickup 20 so that, when the handpan 2 is assembled by fixing the lower segment flange 8 and upper segment flange 10 to the spacer ring 18 with adhesive, the piezoelectric cable pickup 20 is held in place under pressure. Such pressure significantly improves the acoustic performance of the piezoelectric cable pickup 20 and reduces the adverse effect of external sound and interference. An output jack 24 (a 1/4 inch output jack) is installed in a 0.5 inch (1.27 cm) aperture drilled through the lower segment 6 and, in the interior of the lower segment, is soldered to connector 22 in electrical connection with the piezoelectric cable pickup 20.
Figure 2 shows the interior surface of the lower segment 6 before assembly. The lower segment 6 comprises lower tone fields 14, sound hole 16 and output jack 24 soldered to connector 22, itself in connection with the piezoelectric cable pickup 20. The piezoelectric cable pickup 20 extends around the lower segment flange 8. During assembly, the spacer ring 18 (not shown in Figure 2), is adhered to the lower segment flange 8. The spacer ring 18 is less wide than the flange 8 so there is a shelf on the interior side of the flange 8 where the piezoelectric cable pickup 20 is held in place with adhesive and extends around the interior side of the flange 8 adjacent the spacer ring 18.
Figure 3 shows a schematic section, partially exploded for clarity, through part of the rim of the handpan 2. The upper segment flange 10 of the upper segment 4 and lower segment flange 8 of the lower segment 6 each have an SNIP adhesive bead 26 fixing the spacer ring 18 and the piezoelectric cable pickup 20 in place. During assembly, the upper segment flange 10 and lower segment flange 8 are clamped while the adhesive cures (which may take several days). As discussed above, since the spacer ring 18 is shallower in depth (at about 1.5 mm) than the diameter of the piezoelectric cable pickup 20 (at about 1.6 mm), the piezoelectric cable pickup 20 is pinched (the pinch being about 0.1 mm) and so held in place under consistent pressure. Such pressure significantly improves the acoustic performance of the piezoelectric cable pickup 20 and reduces the adverse effect of external sound and interference.
