An acronym is a word or name consisting of parts of the full name's words (like NASA or UNESCO).
The piece is constructed as an accumulation of material from the ultraminor chord to the ultramajor one and back. Such a metaphor of the impossibility of happiness in love, or rather the possibility, but just for a short moment. There is a mistake in the spelling, it’s due to the dedication to the person who gave me a lot of support and love without even knowing it. So, what are ultraminor and ultramajor? These are chords with third quarter-tone lower or higher.
The outcome of the whole piece will be different every time, because the flute and cello pull one sound for a long time and depending on what the pianist plays (I ask to find the dullest overtone on a certain string, the result will be either a conditionally sad consonance or a conditionally happy one). It's just like in life, you never know how you're falling in love with a person will end. in that recording, the end turned out to be quite encouraging.
