Triad Diagrams — La Diminished Cliché (Guitar)

La Diminished ClichéI – ♯I°7 – ii – V

The A Diminished Cliché (A – A#dim – Bm – E) inserts a Half-Whole Diminished passing chord between I and ii, generating a chromatic half-step ascent that defined Tin Pan Alley and bebop vocabulary. The Bebop Major scale smooths the approach to the tonic; Dorian settles over the ii chord. With seventh voicings (AMaj7 – A#dim7 – Bm7 – E7), the chromatic motion sits closer to the inner-voice writing of 1930s jazz harmony.

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 A to A# (ascending half step), A# to B (ascending half step), B to E (ascending 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 E to A 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 Freddie Green-style comping: short, muted chord stabs on beats 2 and 4 at 120-160 BPM. Keep the chords tight and percussive, lifting your fretting hand slightly after each attack to control sustain.
