(10–11–12!)

Music Sharing: Haley & Joey (XHS) Let’s review (and make sure we really know this

stuff!)• Figured Bass vs. chord symbols• Relative vs. parallel minor• Natural Minor• Harmonic Minor• Melodic Minor

More work on…• Primary triads in minor• I, iv, V in minor keys

Some in class work… No class tomorrow!

There are 15 major keys, each with a unique key signature.

For every major key, there is a RELATIVE minor key that has the same key signature.

Each relative minor scale begins on the 6th note (scale degree) of the relative major scale.

The 6th scale degree is the keynote/tonic of the minor scale and the note from which that scale gets its name.

The tonic of a relative minor scale may also be found by descending a minor 3rd or ascending a major 6th from the tonic of the major scale.

The tonic of the relative major scale can be found by ascending a minor 3rd or descending a major 6th from the tonic of the minor scale.

C major / a minor = relative C major / c minor = parallel

Uses only the tones of the relative major scale.

Ascending: A, B, C, D, E, F, G, A

Descending: A, G, F, E, D, C, B, A

Raises the 7th scale degree by a half step when ascending and descending.

The most frequently used of the three types of minor scales.

Ascending: A, B, C, D, E, F, G#, A

Descending: A, G#, F, E, D, C, B, A

Raises the 6th and 7th scale degrees by a half step when ascending.

Descends just like the natural minor scale.

Ascending: A, B, C, D, E, F#, G#, A

Descending: A, G, F, E, D, C, B, A

For all harmonic minor intervals, the following is true:

P1, M2, m3, P4, P5, m6, M7, P8

Compared to all harmonic major intervals:

P1, M2, M3, P4, P5, M6, M7, P8

MAJOR = Major 3rd + minor 3rd (on top) MINOR = minor 3rd + Major 3rd (on top) AUGMENTED = both 3rds are Major

• Raise the 5th by a half step DIMINISHED = both 3rds are minor

• Lower the 5th by a half step• Remember, the 3rd should already be

lowered (made minor)

MINOR:•i, ii∘, III, iv, V, VI, vii∘, I

MAJOR:•I, ii, iii, IV, V, vi, vii∘, I
