La Japanese Circle
IV – V – iii – vi – ii – V – I progression in La major
La Japanese Circle — IV – V – iii – vi – ii – V – I
The A Japanese Circle (D – E – C#m – F#m – Bm – E – A) extends the Royal Road through a full diatonic cycle, touching nearly every chord in the key. Dorian brings modal color to the ii chord, Mixolydian handles the V, and Aeolian settles over the vi resolution. Moving through multiple chord-scale contexts in a single progression makes this a valuable ear-training exercise. With seventh voicings (DMaj7 – E7 – C#m7 – F#m7 – Bm7 – E7 – AMaj7), the harmonic journey becomes richly complete.
Playing in La major
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 D to E (ascending whole step), E to C# (descending minor third), C# to F# (ascending perfect fourth), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to A (ascending perfect fourth). 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 D by perfect fourth.
Capo Transposition
To play in A using familiar open chords: capo 2 with open G shapes; capo 5 with open E shapes; capo 7 with open D shapes. Choose the capo position that gives you the voicings you prefer — lower capo positions produce a fuller sound, while higher positions create a brighter, mandolin-like timbre.
Scales for Soloing
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.
Strumming Pattern
Use D-DU-UDU at 100-120 BPM for a standard pop strum. Accent beats 2 and 4 for a backbeat feel. Vary dynamics between verse (lighter) and chorus (stronger) to build energy.
