How to play Baug on piano
Count keys (black and white) from B: 4 half steps up to D♯ then 4 half steps up to F𝄪. Those 3 keys are Baug.
- Right hand: 1 on B, 3 on D♯ and 5 on F𝄪.
- Left hand: 5 on B, 3 on D♯ and 1 on F𝄪.
- On the keyboard it's white, black and white keys, the same pattern as Eaug and Aaug, so your hand shape carries over.
Baug inversions
- root position: B–D♯–F𝄪. Right hand 1-3-5.

Nobody plays every chord in root position. The inversions let Baug sit wherever the previous chord left your hand.

Baug is an augmented triad: two major thirds stacked, with a raised fifth. Baug is a stepping stone: it often moves on to the IV chord, with the raised fifth rising one more half step. On piano you hear it best with the keys pressed together, then rolled.
