Automatic music playing control device, electronic musical instrument, method of playing automatic music playing device, and non-transitory computer-readable recording medium

A method of playing an automatic music playing device, comprising the steps of:

• probabilistically selecting any one of a plurality of timing types that defines the number of sound emissions;
• probabilistically selecting any one of a plurality of note timing tables that defines sound emission timings, corresponding to the selected timing type;
• and
• instructing a sound source to emit a chord at a sound emission timing based on the selected note timing table.

A non-transitory computer-readable recording medium storing a program of system, wherein the program is configured to allow a computer in an automatic music playing control device:

• to probabilistically select any one of a plurality of timing types that defines the number of sound emissions;
• to probabilistically select any one of a plurality of note timing tables that defines sound emission timings, corresponding to the selected timing type;
• and
• to instruct a sound source to emit a chord at a sound emission timing based on the selected note timing table.
