Mozart · Piano Concerto 20, 1st movement [Organ, Meantone]

We present the first movement from Mozart's Piano Concerto 20 in D minor. The solo part is played at the Organ. Tuning system is 12 notes from meantone, generated by a 697-cent fifth and octave period, spanning the chain from Eb to G#. This is different from the historical tuning used by Mozart, probably 1/6-comma meantone, instead. Sound Production: (c) Claudi Meneghin @ Library of Congress, claim SRu 1 345]


"Lament & Deception", Chacony in 55edo for Two Violins & Cello

This is my Chacony "Lament & Deception" in 55-equal division of the octave (very close to sixth-comma meantone) for two violins and cello. The piece consists in 33 variations on the lament bass, followed by a deceptive cadence. Each section is a diatonic semitone higher than the preceding one, hence we come back to the orginal tonality (C) every 11 steps (since in 55edo 11 diatonic semitones = 1 octave).  


Canon at the Diatonic Semitone on an Ancient Lombard Theme [55edo]

A canon at the diatonic semitone on an ancient Lombard theme, for organ. Tuning is 55-equal division of the octave, close to sixth-comma meantone, a tuning possibly used by Mozart.


The Dominant Seventh Chord: Modulating 7th over the Just Major Triad

We present a tuning comparison about the dominant seventh chord, consisting in various sevenths intervals plus a constant major triad, tuned into just intonation. Sevenths spam the (descending) interval between 1050 cents and 946 cents. This includes the just harmonic seventh at 968 cents.
