Infant Eyes 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 C# to F# (ascending perfect fourth), F# to E (descending whole step), E to D (descending whole step), D to G# (ascending tritone), G# to F (descending minor third), F to B (ascending tritone), B to D (ascending minor third), D to E (ascending whole step), E to A (ascending perfect fourth), A to D# (ascending tritone), D# to D# (ascending unison), D# to A# (descending perfect fourth), A# to G (descending minor third), G to A (ascending whole step). 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 A to C# by major 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.
