Author: Created by Hyacinth (talk) 23:33, 13 December 2009 in Sibelius with midi pitch bend on 70 for 1318.75 cents rather than 1319.44. New version an P8+m2 on 28,70 for 1319.43359375 cents rather than 1319.44.
C major and E minor contrast through their respective notes C and B (in red and orange), each a half step apart or leading tones. The chords share two notes (in blue) however.
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.
