Flying Microtonal Banana is King Gizzard's first-ever experience in microtonal tuning, which features intervals smaller than a semitone and not found in customary Western tuning octaves. 'Earlier this year we started experimenting with a custom microtonal guitar our friend Zak made for (lead singer and guitar player) Stu Mackenzie,' drummer Eric Moore explained. 'The guitar was modified to play in 24-TET tuning and could only be played with other microtonal instruments. We ended up giving everyone a budget of $200 to buy instruments and turn them microtonal.'
