In one sentence: G minor pentatonic with Db, a passing blue note between C and D.

Formula and map

• Formula: 1-♭3-4-♭5-5-♭7.
• Notes: G-Bb-C-Db-D-F.
• The minor pentatonic is G-Bb-C-D-F; Db adds the step between C and D.

Useful fingering

• Right hand up: 1-2-3-4-1-2-3. Down: 3-2-1-4-3-2-1.
• Left hand up: 5-4-3-2-1-3-2. Down: 2-3-1-2-3-4-5.
• Repeat C-Db-D before connecting all six notes of the scale.

Do it, use it, understand it

1. Do it: play C-Db-D three times without leaning on Db.
2. Use it: over G7-C7-D7, let each short phrase end before beginning the next.
3. Understand it: Db is ♭5; it works through contrast with C and D, not as a permanent destination.
4. Listen: in B.B. King's “The Thrill Is Gone,” hear short calls, answers, and rests; use that phrasing as a guide without claiming the recording's key.

Listening and context

Minor-blues vocabulary travelled from singing and acoustic guitar to electric bands. Listen to B.B. King or Muddy Waters for phrasing and the blue note; they are style references, not pitch maps for G.

Common mistakes

• Do not confuse Db with D: play the two notes in sequence and name them.
• As an initial practice, move Db toward C or D when closing a phrase.
• Do not play all six notes every time: try a three-note idea, then leave space.

Checklist

• I can locate Db between C and D.
• I can play an ascending and descending octave with a steady pulse.
• I use C-Db-D as a passing gesture.
• I can answer a phrase after a rest.
