Revision as of 00:25, 30 September 2021

Garibaldi temperament is a 7-limit (and higher) temperament of the schismatic family. It is an extension of helmholtz temperament beyond the 5-limit but with the same simple chain-of-fifths structure (so that standard notation may be used). As in helmholtz temperament, 5/4 is mapped to the diminished fourth (e.g. A-D♭), and the new mapping specific to garibaldi is that 7/4 is mapped to the double diminished octave (e.g. A-Abb). This makes garibaldi a marvel temperament.

Immediate 11-limit extensions include cassandra (41&53), mapping 11/8 to +23 fifths, andromeda (29&41), mapping 11/8 to -18 fifths, and helenus (53&65d), mapping 11/8 to -30 fifths.

Interval chain

In the following table, prime harmonics are in bold.
