2048 equal divisions of the octave (abbreviated 2048edo or 2048ed2), also called 2048-tone equal temperament (2048tet) or 2048 equal temperament (2048et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 2048 equal parts of about 0.586 ¢ each. Each step represents a frequency ratio of 2^1/2048, or the 2048th root of 2.

Theory

2048edo has an excellent perfect fifth, which derives from 1024edo. It tempers out the breedsma (2401/2400) in the 7-limit, and supports the rank-3 breed temperament.

2048edo is usable as high as 43-limit, with the 2048f val regular temperament having an error of 0.023 cents (0.04 edosteps) per octave, and the no-13's limit patent val is unambiguous and has an error of only 0.019 cents/octave.

In the 5-limit, it supports monzismic temperament. In the 11-limit, 2048edo tempers out the quartisma.
