Dolphin Dance in A

Dolphin Dance in A

Herbie Hancock's flowing composition with ever-shifting key centers, creating the illusion of a dolphin leaping between tonal areas.

Dolphin Dance in A

A major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through A to G (descending whole step), G to G# (ascending half step), G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to G# (ascending whole step), G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to D (descending major third), D to G (ascending perfect fourth), G to C (ascending perfect fourth), C to D# (ascending minor third), D# to G# (ascending perfect fourth), G# to C# (ascending perfect fourth), C# to E (ascending minor third), E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to D# (ascending half step), D# to G# (ascending perfect fourth), G# to C# (ascending perfect fourth), C# to B (descending whole step), B to E (ascending perfect fourth), E to E (ascending unison). A half-step bass movement creates a strong leading-tone pull that demands resolution. The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from E to A by perfect fourth.

Scales for Improvisation

A major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, A Mixolydian adds the flat seventh for an authentic blues-rock edge.
