From Test-Scratch-Wiki

The note names are written on the keys. Notes written in the two most common clefs (Treble clef and Bass clef) are connected to the piano. All notes can be written in an infinite number of ways. The most common enharmonic notes are included. A line going from a long red box means the notes go to the same key on the piano. Even though the drop-down keyboard shows only two octaves of notes (48 to 72), a number can be put in manually to get any note from 1 to 127. To change octaves, simply add or subtract 12.

An instrument is a musical instrument that is used in Scratch with the Play Note () for () Beats block to produce a note from a various instrument or a sound effect of various pitch.

With Musical Instruments

There are many musical instruments that are available for use. Most of these use notes (such as the clarinet), but there are also others that are percussion instruments and do not require notes (such as drums or the woodblock). In these cases, the notes control the pitch of the instrument.

With Sound Effects

Scratch gives a satisfactory range of sound effects for use; these include everyday sounds such as a telephone ring, and sounds for other genres, such as a gunshot. Obviously, these sound effects are not controlled by notes in the same way as the above; rather, with these instruments, the given note affects the pitch of the sound.
