Bb7 chord for guitar with diagrams, fingerings and notes.
The Bb7 is a dominant chord and equivalent to A sharp 7th. It consists of four notes, though depending on the instrument, some notes may be doubled or tripled. Since the root as well as the 5th and 7th are absent among the open strings in standard tuning, there are few simple fingerings in open positions. Because of that, the chord is often played as a barre chord or in closed positions.
The notes that the Bb7 chord consists of are Bb, D, F and Ab. These represent the root, major third, perfect fifth and minor seventh intervals. Notice that the third or the fifth is sometimes omitted.
1st inversion: Bb7/D (means that D is the bass note).
