'''A-Team''' is a 2.9.21 temperament generated by a tempered zo fourth ([[21/16]]) with a size ranging from 461.54¢ (5\13) to 470.78¢ (the pure value for 21/16). A-Team is one of several [[oneirotonic]] temperaments. It can be viewed as every other note of 2.3.7 latrizo or "[[slendric]]" temperament. Any EDO that has an interval within the range 461.54¢ to 470.78¢ will support A-Team. Three 21/16's are equated to one 9/8, which means that the [[color notation|latrizo]] comma (1029/1024) is tempered out. Its name is a pun on the 18 notes in its proper scale, which is a [[13L 5s]] MOS. It is named thus because [[18edo]] supports the temperament.

It's natural to consider A-Team a 2.9.21.5 latrizo & gu temperament by equating two 9/8's with one 5/4, tempering out 81/80. Generators optimized for tempering out 81/80 also tend to generate the melodically best scales. This temperament generates [[3L 2s]], [[5L 3s]], and [[5L 8s]] MOSes, most notably the 8-note "oneirotonic" MOS. Any EDO with an interval between 461.54¢ and 466.67¢ can be reasonably said to support 2.9.21.5 A-Team.

[[13edo]], [[18edo]], [[31edo]], and [[44edo]] are all valid tunings.
This article is mostly theoretical and based on regular twmperament theory. For other approaches to using A-Team, see [[5L 3s]].
