24-tet scale on C (50 cent steps). Easley Blackwood, Jr.'s notation for 24 equal temperament. As only "ups" are used, there are no three-quarter flats and quarter flats are enharmonically spelled (Dd = C#↑). Pitches are split into two groups of 12. MIDI pitch bend is correct for intervals.
Wolfgang Amadeus Mozart: Great Mass in C minor, K. 427 Ferenc Fricsay, Berlin Radio Symphony Orchestra, Chor der St. Hedwigs-Kathedrale Berlin, Maria Stader, Hertha Töpper, Ernst Haefliger, Ivan Sardi.
Recording of my kalimba tuned to c-major (give or take a few cents), striking the lowest possible note. Recorded on a rode nt1-a through a scarlett 2i2 interface. Noise-reduced for clarity.
