Minor scale | Made up of tones & semitones. The 3rd degree of the scale is FLAT |
Intervals | The distance between any 2 notes. The LOWEST note counts as number 1. They are: 1-1 UNISON: 1-2 Second: 1-3 Third: 1-4 Fourth: 1-5 Fifth: 1-6 Sixth: 1-7 Seventh: 1-8 OCTAVE |
Unison | Two sounds sharing the identical note. |
Cadence | A PAIR of chords that finish a phrase or section of music. |
Perfect cadence | Chords 5 - 1, V-I, or dominant to tonic. FULL stop - the music could end here. |

Sharp (#) | Raises a note by a semitone |
Flat (b) | Lowers a note by a semitone |
Relative Major | Shares the key signature but the SCALE starts a minor 3rd HIGHER |

Cycle of Fifths | A wheel that shows each Key Sig. in turn by counting around 5 notes. C - G - D - A (#) or C - F - Bb - Eb (b) |
