What Number Is Middle C

Computer Music (MUSC 216)
MIDI Note/Cardinal Number Chart

In that location are TWO conventions for numbering keys (notes) in MIDI. The well-nigh common is the one below where Centre C (note #threescore; $3C) is C3 (C in the 3rd octave). Withal, some other convention was adopted by Yamaha Corp. for their synthesizer products which parallels the Octave Designation Organisation used in Music Education formulated by the Acoustical Society of America. In that convention, Middle C is designated "C4". The "C3 Convention" is the about commonly used octave designation arrangement on standard MIDI keyboards and this is the convention we will use for this class.
