Notes

B♭ – D – F – A – C – E

Formula

1 – 3 – 5 – 7 – 9 – #11

Practice Note

This Lydian major-nine sonority works as a stable tonic or IV-chord color rather than requiring dominant resolution. The 5th is a common omission in piano voicings; #11 avoids the close-semitone clash between a major 3rd and natural 11.
