Bb Minor Arpeggio

What is a Bb minor arpeggio?

It is the Bb minor chord played one note at a time: Bb Db F, the 1, b3, 5 of Bb minor. Play the notes together and it is the chord; play them in sequence and it is the arpeggio. Same three notes, so wherever the chord fits, the arpeggio fits too.

Bb minor vs Bb major arpeggio

One note apart. The minor arpeggio has the 3rd, Db; the major has D. The root and the 5th are the same, so a minor shape becomes the major shape by moving one finger up a fret.

Which keys use the Bb minor arpeggio

Bb minor is a chord in every key whose scale contains Bb, Db, F. It is the i of Bb minor, and it appears in these keys too, under a different numeral each time:

• Db major — where it is the vi
• Eb minor — where it is the v
• F minor — where it is the iv
• Ab major — where it is the ii

The Bbm7 arpeggio

Add the 7th and the arpeggio becomes Bb Db F Ab — Bbm7. Four notes instead of three, the extra one sitting a whole step below the root, which is what gives it the jazz and soul colour. Every shape below extends to it by adding one note per octave.

How to practice the Bb minor arpeggio

1. Hold a Bbm chord and pick its notes one at a time, low to high and back. That is the arpeggio in its simplest form.
2. Open the arpeggio generator in this key and step through the sweep shapes. Each is the same three notes laid out for one picking motion.
3. Play it over a two-chord vamp — Bbm to Db — and switch arpeggios when the chord changes. That is the whole skill of playing the changes.
