The scale you described starts on D natural and follows this sequence: D, E, F, G, A, B♭, C, D.
To determine the type of scale, let's analyze the intervals:
- D to E: whole step
- E to F: half step
- F to G: whole step
- G to A: whole step
- A to B♭: half step
- B♭ to C: whole step
- C to D: whole step
This pattern of whole and half steps corresponds to the D natural minor scale, which features a lowered 6th degree (B♭ instead of B natural) when compared to a major scale.
So the correct response is minor (specifically, it indicates a natural minor scale).
