So more keys allows composers to cover a wide range of notes to compose their music.Įxtra piano keys eliminates the possibilities of limitation. Simple, as you know each keys have their particular notes, so more keys means more notes. Your first question should be “Why Pianos have 88 keys ?” (9 extra bass keys) Why do some pianos have more keys ? Some less mainstream pianos even has more then 88 keys.Ī fine example will be The Beleura from Stuart and Sons which has 108 keys and is also self-proclaimed as the world’s first 108 keys piano.Īnother noteworthy 97 keys piano is Bösendorfer Imperial Concert Grand Piano model 290. But later the instrument was refined more and ended up with 60 keys.īut 60 keys of harpsichord were not enough as its limit the composers to only 5 octaves range.
The earlier version of harpsichord were only have 40 keys. If you look back at the history of pianos you will find that pianos were being experimented with whole new design and working mechanism through 18 th and 19 th century.Īlthough the core working mechanism was never changed since the hammered dulcimer but the design and other mechanism have shifted a lot since the beginning.Īt the beginning of the journey of today’s modern piano the first instrument (which was modified later) was harpsichord. Brief Piano History - The progress with Keys
The number of keys on a standard piano (acoustic / digital piano) is 88.īut it was not always the case. So does this make pianos string instrument? (percussion instrument) I will answer this in the end of this post.Ĭoming to the main question now. The vibration of the strings produces the sound we hear. Real acoustic pianos have strings in their working mechanism. I am also going to expand this question slightly a bit and also explain the number of strings pianos have.
