Heartland

From Xenharmonic Wiki
Jump to navigation Jump to search

The heartland is the name given to the collection of temperaments that are children of or related to the heartland temperament, the 2.3.7.11.19 subgroup temperament tempering out both 243/242 and 1083/1078, and its full 19-limit extension, heartsphere. The term "heartland" loosely means "interior part."

For extending the heartland temperament to the 2.3.5.7.11.19 subgroup, it is natural to temper out 361/360, 441/440 or 540/539, which makes a weak extension of the jove temperament. For extending to the 2.3.5.7.11.13.19 subgroup, tempering out 364/363 gives an excellent tuning.
