Lyrics by Gayaman Disanayake and music by Rohana Weerasinghe.
This song contains B diminished chord in interlude.Diminished chords are dissonant and unstable.They give a feeling of incompleteness.They usually ends up with half step up major chord or the relative minor of that major chord .Usually we don't stay on them too long.
There are 3 types of diminished chords.
Diminished Chord - 1 b3 b5
Half Diminished 7th - 1 b3 b5 b7
Full Diminished7th - 1 b3 b5 bb7
C Diminished Chord C - Eb - Gb
C Diminished 7th (Half) C - Eb - Gb - Bb
C Diminished 7th (Full) C - Eb - Gb - A
If this is geek to you Don't worry just play the chord. :) There are lot of ways to play B dim chord.But I think this shape is the easiest way to play in this occasion considering the neighboring D minor and Bb Chords.
