What mode starts on G and has 2 flats, Bb and Eb?
The mode that starts on G and includes two flats, Bb and Eb, is the G Aeolian mode, also known as the natural minor scale. The notes in the G Aeolian scale are:
- G, A, Bb, C, D, Eb, F, G
This aligns with the key signature of Bb major but starts on G, making it the relative minor scale or Aeolian mode based on G. Thank you for your clarification.
