A-Team tunings (with generator between 5\13 and 7\18) have L/s ratios between 2/1 and 3/1. | A-Team tunings (with generator between 5\13 and 7\18) have L/s ratios between 2/1 and 3/1. | ||
EDOs that support A-Team include [[13edo]], [[18edo]], and [[31edo]]. | |||
* 18edo can be used for a large L/s ratio of 3, (thus 18edo oneirotonic is distorted 17edo diatonic), or for nearly pure 9/8 and 7/6. | |||
* 31edo can be used if a near-just 5/4 is desired. | |||
A-Team can be tuned by ear, by tuning a chain of pure harmonic sevenths and taking every other note. This corresponds to using a generator of 64/49 = 462.34819 cents. A chain of fourteen 7/4's are needed to tune the 8-note oneirotonic MOS. This produces a tuning close to 13edo. | A-Team can be tuned by ear, by tuning a chain of pure harmonic sevenths and taking every other note.
