Tastiera (Italian for ‘keyboard’) is a Dashboard widget that lets you use your computer keyboard as a piano keyboard.

Unlike other products, this widget provides a range of 3 octaves (11/2 octave on either side of middle C). Also, the Tasiera widget itself will clearly show which key corresponds to each note, even for non-QWERTY, non-US keyboards.

NOTE: This is a preview version that will expire after June 2008.
