AP Music Theory Chapter 2 – Part 3
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.
Non-Diatonic Scales • Chromatic Scale is a nondiatonic scale consisting entirely of half-step intervals. • Has no tonic. Each note equidistant from the next.
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.
