而钢琴是一种源自西洋古典音乐的键盘乐器。由88个琴键(52个白键，36个黑键)和金属弦音板组成。音域范围广，从A2(27.5Hz)至c5(4186Hz)，几乎包括了乐音体系中的全部乐音。The piano is a keyboard instrument derived from Western classical music. It consists of 88 keys (52 white keys, 36 black keys) and a metal string soundboard. The range of sound ranges from A2 (27.5Hz) to c5 (4186Hz), including almost all the tones in the tone system.
钢琴普遍用于独奏、重奏、伴奏等演出，作曲和排练音乐十分方便。演奏者通过按下键盘上的琴键，牵动钢琴里面包着绒毡的小木槌，继而敲击钢丝弦发出声音。Pianos are commonly used in solo, ensemble, accompaniment, etc. It is very convenient to compose and rehearse music. By pressing the keys on the keyboard, the player pulls the muslin in the piano and then taps the wire string to make a sound.
在目前的现有技术中，往往通过激光等方式将乐谱或者音符投影在钢琴琴键或者空白处，但由于激光容易伤眼且制作成本较贵，并不能带给弹奏者良好的弹奏体验，而在弹奏时，还需要对乐谱或是音符进行思考，适合那些对五线谱有一定了解的弹奏者。In the current prior art, a musical score or a note is often projected on a piano key or a blank by a laser or the like, but since the laser is easily injured and expensive to manufacture, it does not give the player a good playing experience. When playing, you need to think about the scores or notes, suitable for those who have a certain understanding of the staff.
而在目前的情况下，一个刚刚接触钢琴的人是无法不通过其他人指导而直接开始弹奏钢琴的，需要先学习五线谱，熟悉如何弹奏等等， 过程十分复杂，而并没有一种能够根据投影器打在钢琴上的提示从而直接进行钢琴演奏的一种投影式钢琴指引***以及相应地控制方法。In the current situation, a person who has just touched the piano can't start playing the piano directly without the guidance of other people.
