緩和[編集]

53平均律は、ディエシス (128:125)、7限界のコンマ (64:63)、シントニックコンマ (81:80)を含む音程を緩和していない。

53平均律は、32805:32768(スキスマ、純正5度8個と純正長3度1個を重ねた音程と5オクターヴの差分)、15625:15552(クライスマ英語版、純正短3度を6個重ねた音程と3:1の音程の差分)、121:120(大小2つの11限界の中立2度の差分)、225:224(七限界のクライスマ、16:15の半音の2倍と8:7の全音の差分)、325:324(10:9の小全音の2倍と16:13の中立3度の差分)、352:351(13:11の短3度とピタゴラス音律の短3度の差分)の周波数比を緩和する。
