Re: WAYLTL 2025!

Extending the idea of "solo piano" both with supplementary instruments
& techniques for playing a wider range of infrachromatic pitches,
composer-pianist NYC-based Phillip Golub returns:

"To achieve such novel tunings on an acoustic piano, a feat of
engineering from Greyfade founder Joseph Branciforte and the piano
technicians at Yamaha Artist Services in Manhattan was required.
Golub prepared a performance of the piece on a MIDI keyboard,
capturing his unique approach to phrasing and dynamics. That
performance was then played back through a Disklavier -- Yamaha's
proprietary system for mechanical player piano-style playback --
onto a microtonally-tuned acoustic piano in two separate layers.
Each recording layer captured 11 of the 22 pitch classes, allowing
the piano to be carefully retuned between passes, a solution devised
to avoid excessive strain on the instrument. When combined, the two
layers created a seamless acoustic representation of Golub's
performance on a Yamaha CFX concert grand piano -- albeit one with
22 notes per octave."
