What is the Bb Harmonic Minor Scale?
The harmonic minor scale takes the natural minor and raises the 7th degree by a half step, creating a leading tone that pulls strongly back to the root. That raised 7th also produces an augmented 2nd interval between the 6th and 7th degrees — the dramatic, almost "neoclassical" sound you hear in Yngwie Malmsteen and Baroque music alike. Here's how the Bb Harmonic Minor Scale lays out on the fretboard. This scale is enharmonically equivalent to A# Harmonic Minor.
Notes and Positions
Natural minor with raised 7th. Classical and neoclassical. On guitar, you can treat this as both a lead vocabulary and a way to see chord tones inside common shapes. Start with one box, then connect it to the nearest root on the next string set. In the key of Bb, the notes are: Bb, C, Db, Eb, F, Gb, A.
How to Use It
You'll often hear it in Classical, Neoclassical Metal, and Middle Eastern. A good way to internalize the sound is to sing the root, then sing a few scale degrees before you play them.
Start by playing one position slowly and saying the note names or degrees out loud. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
