How Deep Is The Ocean in D
How Deep Is The Ocean in D
Irving Berlin's ballad moves through a striking series of fourth-based harmonic motion that opens up Dorian color on the minor passages, Bebop Major lyricism on the major sections, and Harmonic Minor tension on the minor dominant resolutions. The fourth-cycle harmonic logic gives the tune an unusually strong sense of forward momentum for a ballad. Voice leading across the fourth-based changes is the central harmonic challenge.
How Deep Is The Ocean in 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 B to C# (ascending whole step), 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 B (ascending perfect fourth), B to E (ascending perfect fourth), E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to A (descending perfect fourth), A to D (ascending perfect fourth), D to G (ascending perfect fourth), G to B (ascending major third), B to E (ascending perfect fourth), E to F# (ascending whole step), F# to G (ascending half step), G to C (ascending perfect fourth). 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 C to B by half step.
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.
