The Sonny Downs Quartet presents Heptology

The Sonny Downs Quartet presents Heptology, a suite of pieces exploring the number seven.
Just intonation is used throughout, with a focus on septimal intervals.
The time signatures are all based on the number seven, and phrases of seven bars are used.
Heptology was composed over 2021 to 2023, using a Buchla 200e modular synthesizer, in Coffs Harbour, Australia. The pieces were all recorded live, with no edits or cuts. The album has been lovingly mastered by Marly Lüske in Brisbane.
Available on Bandcamp and streaming everywhere else.
