O Que Será 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 D (ascending unison), D to D (ascending unison), D to D (ascending unison), D to A (descending perfect fourth), A to A (ascending unison), A to A (ascending unison), A to B (ascending whole step), B to G (descending major third), G to G (ascending unison), G to G (ascending unison), G to G (ascending unison), G to A# (ascending minor third), A# to A# (ascending unison), A# to E (ascending tritone), E to A (ascending perfect fourth), A to A# (ascending half step), A# to A# (ascending unison), A# to F (descending perfect fourth), F to C# (descending major third), C# to A (descending major third), A to G (descending whole step), G to D (descending perfect fourth), D to E (ascending whole step), E to C (descending major third), C to C (ascending unison), C to C (ascending unison), C to C (ascending unison), C to D# (ascending minor third), D# to D# (ascending unison), D# to A (ascending tritone), A to D (ascending perfect fourth), D to D# (ascending half step), D# to D# (ascending unison), D# to A# (descending perfect fourth), A# to F# (descending major third), F# to D (descending major third), D to E (ascending whole step), E to A (ascending perfect fourth), A to E (descending perfect fourth), E to E (ascending unison), E to E (ascending unison), E to F# (ascending whole step), F# to F (descending half step), F to F (ascending unison), F to B (ascending tritone), 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 predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from E to D by whole 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.
