Which key is my instrument in?

For picking Other in Settings

Some instruments don't sound the note they read. Play a written C on a clarinet and you hear a B flat: the clarinet is a B flat instrument. Glisso listens for the note that should sound, so it needs to know your key, which octave you sound in, and the clef your music is written in.

Find your instrument

Instruments named in Glisso's own list already know all three. Brass players should pick their instrument from the Brass list, which also knows the fingerings.

Not on the list?

Key: play a written C and look at a tuner. The note it shows is your key. If it shows C, you play in C.
Octave: most instruments are Normal. Lower is for an instrument that sounds an octave below the others in its key, like a tenor sax next to a clarinet. Higher is for one an octave above, like a piccolo.
Clef: the clef at the start of your music.

Your band or orchestra director will know all three.

Why it matters

A flute and a clarinet reading the same written C play two different notes. Glisso hears what you play and compares it with what you read, so it has to know which note your written C really is.
