The meter
EgejkiMajki.ly: \time 3,2,2,3,2 12/8
that I use actually has a duplet substructure, corresponding to
\time #'(\tuplet 2/3 3 2 2 \tuplet 2/3 3 2) 12/8
Then, as an example of irrational meters, and how to engrave them in LilyPond,
I wrote
the time signatures (8+2√5)/8 and (6+4√2)/8, derived from approximations of
3/2: the first the somewhat higher golden ratio (1+√5)/2, and the second
somewhat lower √2. From the musical point of view, the idea is to erase the
exact ratios in “\time 3,2,2,3,2 12/8”, as in real performances, there is quite
a deviation.
Then for the MIDI output, I approximated these respectively by
\time 5,3,3,5,3 19/8
\time #'(7 5 5 7 5) 29/8
One way to find such rational approximations is by the use of continued
fraction convergents.
When I compile these examples now, I get an error that the character ‘√’ is not
present in the font emmentaler-16.
