Aquarela do Brasil in C

With no sharps or flats, C major is the theoretical home base on guitar. The open G, B, and high E strings all belong to the C major chord, creating natural sustain. C is a beginner-level key on guitar because the open B and high E strings ring within the scale, and every basic chord uses familiar open shapes. Beginners will find this key approachable since most chords use open voicings with minimal stretching.

Voice Leading

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

Scales for Improvisation

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