Tonality

• Organized system of tones in which one tone (the TONIC) becomes the central point to which the other tones are related.

• Another word: tonal center.

Key• Tonal system based on the major and minor

scales. • However, tonality can be present scales other

than major and minor.

Pentatonic Scales

• 5-tone scale• A gapped scale, one that contains intervals of

more than a step between adjacent pitches. • Incomplete major scale• The sequence of black keys on the keyboard

coincides with the interval relationship of the pentatonic scale.

Pentatonic Scales

Non-Diatonic Scales

• Chromatic Scale is a nondiatonic scale consisting entirely of half-step intervals.

• Has no tonic. Each note equidistant from the next.

CHROMATIC SCALE

WHOLE TONE SCALE

• Six-tone scale made up entirely of whole steps.

BLUES SCALE

• Chromatic variant of the major scale with a flat 3rd and a flat 7th.
