To play the chromatic scale on the alto saxophone, players should choose a starting point and play each semitone until they have reached the same note one octave up. The chromatic scale is a scale that uses every semitone within a specific range, usually one octave.
The chromatic scale is especially beneficial for jazz players as it helps develop a feel for the fingering and sound for each semitone of the musical spectrum. This is helpful for soloing, as jazz music can use a variety of different notes to produce colorful and even atonal harmonies. It can also be useful for practicing rhythm and articulation.
Players sometimes find it helpful to reference a fingering chart while they practice.
