The only notable low-harmonic-entropy scale for this MOS pattern is sensi, in which two generators make a 5/3. The harmonic entropy of sensi[5] is still fairly high relative to other pentatonic scales, such as meantone. It's also improper.

Names

The TAMNAMS system uses the name antipentic as it uses opposite step sizes to the “classic” pentatonic scale (2L 3s).

Modes

• 4|0 LLsLs
