These scale and arpeggio patterns are based upon the premise that instrumentalists need to know how scales and arpeggios look in order to be fluent sight-readers and improve finger technique. They are divided into low, middle and high registers. They progress through the cycle of fourths to include 15 keys, including the enharmonic keys. The high register patterns use tenor and treble clefs. Accidentals are used for each key rather than key signatures. Scales included are: majors with tonic arpeggios, harmonic minors with minor arpeggios, melodic minors with tonic seventh arpeggios, chromatics, whole tones with augmented arpeggios, octatonics (diminished scales) with diminished seventh arpeggios, pentatonic and blues scales.
