Is there an instrument with more than 1000 strings?

Yes, there are instruments with more than 1000 strings. One such instrument is the grand piano. A standard grand piano has 88 keys, each of which is associated with multiple strings. The number of strings per key varies depending on the note and the specific design of the piano, but it is common for there to be three strings for each key in the middle of the keyboard, and two strings for each key in the bass and treble sections. This means that a grand piano typically has around 220 to 230 strings. However, there are some larger concert grand pianos that have even more strings, with some reaching over 1000 strings.
