I have two that come to mind:
1) minor7, 9, 11. So for example, Bbm7,9,11.
The notes would be Bb C# F Ab C E. This chord is used ubiquitously in jazz, neo soul, and R&B music for the keyboard.
2) the second chord of the main last segment of Rachmaninoff Piano Concerto No2. I don’t know what it’s called but the notes would be something like (if it were in key of Bb): Bb B Eb F Ab.
Let me know if I’m making sense, I can also record me playing it, which probably sounds better than my description🙂
