How Deep Is the Ocean? in D

Key of D

D major is one of guitar's most resonant keys. The open D string acts as a droning root, and the open A string provides the fifth. This gives D-based strumming a wide, ringing quality that flatpicks and fingerpicks love. D is a beginner-level key on guitar because the open D and A strings provide a powerful bass foundation, and the open high E is the 2nd scale degree adding brightness. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

The bass line moves through D to A (descending perfect fourth), A to D (ascending perfect fourth), D to B (descending minor third), B to A (descending whole step), A to E (descending perfect fourth), E to A (ascending perfect fourth), A to C (ascending minor third), C to G (descending perfect fourth), G to F (descending whole step), F to F (ascending unison), F to A# (ascending perfect fourth), A# to G (descending minor third), G to C (ascending perfect fourth), C to D (ascending whole step), D to G (ascending perfect fourth), G to F (descending whole step), F to G (ascending whole step), G to D (descending perfect fourth), D to A (descending perfect fourth), A to F (descending major third). 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 F to D by minor third.

Scales for Improvisation

D 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, D Mixolydian adds the flat seventh for an authentic blues-rock edge.
