Moment's Notice in La
Moment's Notice in La
Coltrane's composition moves through a rapid succession of ii-V-I cycles in multiple keys, demanding instantaneous mode shifts between Dorian, Mixolydian, and Bebop Major. The relentless harmonic movement leaves no room for tonal ambiguity — every two bars the tonal center shifts. Mastering this tune builds the kind of harmonic reflexes that define advanced bebop playing.
Moment's Notice in La
A major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through A# to D# (ascending perfect fourth), D# to B (descending major third), B to E (ascending perfect fourth), E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to G (ascending perfect fourth), G to G# (ascending half step), G# to C# (ascending perfect fourth), C# to A (descending major third), A to D (ascending perfect fourth), D to G (ascending perfect fourth), G to F# (descending half step), F# to E (descending whole step), E to A (ascending perfect fourth), A to D (ascending perfect fourth), D to C# (descending half step), C# to F# (ascending perfect fourth), F# to C (ascending tritone). 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 A# by whole step.
Scales for Improvisation
A 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, A Mixolydian adds the flat seventh for an authentic blues-rock edge.
