Virtual cello
The notes are recordings of one real cello played with the bow, from the open C string at the bottom up to the E more than three octaves higher. Each note is taken from the string a cellist would play it on, so the low notes sound dark and the high ones sing.
Plug a controller in and the cello's full range sits under your hands, from the deep bass notes to its singing top. On letter keys, the arrow keys move you down and up.
No download, no account and no sign-up. The cello is played by your own browser, on your own machine, and a recording you make stays there.
