BbEbG

BbEbG refers to the three pitch classes B-flat, E-flat, and G. When regarded as a harmony, these notes form the Eb major triad (Eb–G–Bb). The particular order Bb–Eb–G represents the triad in second inversion, because the bass note is the fifth of the triad (Bb) while the other two notes are Eb and G above it. In chord-symbol notation, this can be described as Eb major in second inversion or Eb/Bb.

From interval perspective, the triad contains a major third between Eb and G and a perfect fifth between Eb and Bb. The arrangement Bb–Eb–G highlights the fifth in the bass, a common voicing in various musical contexts, including classical, pop, and jazz, where different inversions of the same triad are used to achieve particular bass lines or voice-leading effects.

In pitch-class set theory, the collection {Bb, Eb, G} is transpositionally equivalent to the major triad {0, 4, 7}, which is the prime form of a major triad. This reflects that, regardless of the specific spelling, the sonority corresponds to a familiar harmonic structure rather than an exotic or unique chord.

Usage and context vary by genre, but BbEbG as a voicing commonly contributes a stable tonal color due to its Eb major triad core and the bass note that defines the inversion.
