The scales of G minor and B minor are tested in the Grade 3 Trinity and ABRSM Music Theory exams.
View the Complete Grade 3 Music Theory Video CoursesIn this lesson we will look two types of minor scales, the harmonic minor and the melodic minor in the keys of G minor and B minor.
- The harmonic minor has the pattern T-S-T-T-S-3S-S (3S = 3 semitones).
- The melodic minor has one pattern on the way up and another on the way down:
- Ascending (from bottom): T-S-T-T-T-T-S
- Descending (from top): T-T-S-T-T-S-T
If you find it difficult to remember all the patterns of tones and semitones, try this method instead: learn the notes of three types of minor scale for A minor – they are easy to learn. Then write out the A minor scale and calculate whether each step is a tone (whole step), semitone (half step) or three semitones (three half steps). Then use the same pattern as a guide, to write out a new scale in a different key.
