Minor scale — Wikipedia:

In music theory, the term minor scale refers to three scale patterns — the natural minor scale (or Aeolian mode), the harmonic minor scale, and the melodic minor scale (ascending or descending)[1] — rather than just one as with the major scale.

I was listening to a podcast yesterday. There were two speakers, both claim to have been classically-trained with degrees in music theory and/or music performance.

Neither of them could “speak” the difference between the “minor” scales

• natural
• harmonic — seventh degree raised semitone — leading tone
• melodic — raised sixth and seventh degree ascending, not raised descending

You’ll know it when you hear it.

Roman numeral analysis — Wikipedia:

In music, Roman numeral analysis uses Roman numerals to represent chords. The Roman numerals (I, II, III, IV, …) denote scale degrees (first, second, third, fourth, …); used to represent a chord, they denote the root note on which the chord is built. For instance, III denotes the third degree of a scale or the chord built on it. Generally, uppercase Roman numerals (such as I, IV, V) represent major chords while lowercase Roman numerals (such as i, iv, v) represent minor chords (see Major and Minor below for alternative notations); elsewhere, upper-case Roman numerals are used for all chords.[2] In Western classical music in the 2000s, Roman numeral analysis is used by music students and music theorists to analyze the harmony of a song or piece.

A great place to find notation conventions. NNS gives me such grief…

Ab Major / Ab Bb C Db Eb F G Ab / 4b Bb Eb Ab Db —
F minor / F G Ab Bb C Db Eb F G / 4b Bb Eb Ab Db —

Every morning. Find the scale on the piano. Do the I / IV / I / V / V7 / I chords. Do the i / iv / i / V / V7 / i chords,

I like doing the i , i sus4, V chords as well.

I should really remember to fire up Logic Pro X with my “Quick Record” template before I hit the keyboard. The template has an audio track set to my Advanced Audio DM20 (RE20ish) and a MIDI track ready to record (E-piano).
