How each scale is laid out
Each measure of the scale starts with a quarter note on beat one, then eighth notes, up and back down. The arpeggio follows in triplets, and the scale ends on a whole note. With 2 octaves on, a scale that would go past the range on this sheet is printed in one octave and marked "1 octave".
Keys with two names
D♭ and C♯ major sound the same, and so do G♭ and F♯, and B and C♭ (and their relative minors). Use the spelling buttons to print the one your music uses.
Concert pitch and your written key
Band directors name scales by concert pitch, so the whole band plays the same notes together. The tenor sax is a transposing instrument: concert B♭ is written as C for you. Each scale is titled by its concert name, with your written key beside it.
Practicing scales
Use a metronome. Start slow enough to play every note clean and in tune, and speed up only once you can play the scale twice in a row without a mistake. Say or think the note names as you play, and learn the fingerings with them, so both are automatic by the time the scale is fast.
