Take The A Train in La

Take The A Train in La

Take The A Train in A — Duke Ellington's anthem, defined by its signature #IV chord (II7#11). Use Lydian Dominant over that chord for the characteristic uptown sound, Bebop Major everywhere else. Changes: AMaj7 – B7 – Bm7 – E7 – DMaj7.

Take The A Train 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 B (ascending whole step), B to B (ascending unison), B to E (ascending perfect fourth), E to D (descending whole step). The predominantly stepwise bass motion creates smooth, connected voice leading. When the progression loops, the bass returns from D to A by perfect fourth.

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.
