Most modern pianos have a row of 88 black and white keys (52 white keys for the notes of the C Major scale (the notes C, D, E, F, G, A and B) and 36 shorter black keys, which are raised above the white keys, and set further back on the keyboard.
There's even a piano made today--the BÃ¶sendorfer Imperial Concert Grand--which has 96 keys; the bass notes go all the way down to C. It's nine-and-a-half feet long and weighs almost a ton. Q: How many strings does a piano have? A: It depends on the piano. Each note has three strings in the treble, two strings in the tenor and part of the bass, and only one in the very low bass. One of ours has 65 trebles (X 3=195), 12 tenor/bass (X 2=24), and 11 single low bass, so it comes out to 230. But that's a large grand, so you need to look in your piano and count them up.
