Sgutsis's work on tuning theory includes:
*Properties of particular equal temperaments: 17edo, 19edo, 22edo, 27edo, 31edo, 34edo, 41edo
and 46edo .
*Horograms and MOS scales
*Noted that 12edo, 19edo, 22edo, 31edo, 41edo and 46edo were accurate because of the Riemann zeta function, and concluded that 41edo was the best for approximating 13-limit just intonation (specifically for circulating instruments like organs)
