THE DIATONIC SCALE

• A scale is a set of notes ordered by pitch. It can be ascending or descending
• The diatonic scale is made of seven notes (high 'do' is repeated)

• It has five tones (or whole steps) and two semitones (or half steps)

• The semitones in the diatonic scale are between the notes mi-fa and si-do

• If you look at the keys of a piano you can see the distance of tone and semitone easily. There is no black key between the semitones.
