Intonation Information
As I now have a semi-autonomous
microtonal website
this page is going to be more specialist, dealing with
my own ideas.
If you've got a PC, have a look at my
software that should help you to hear this stuff.
Now, here are some pages that help with the practicalities of
making music in alternative tunings:
- 5-limit scales
- A complete list of scales that fulfil certain criteria
about 5-limit harmony.
- 7-limit scales
- Some 7-limit scales fulfilling similar criteria. Not a
complete list, because there's so much variety in
7-limit harmony. Includes my "blues scales" which are
well worth a listen.
- Scales on a decimal lattice
and decimal notation
- I devised my decimal notation and lattice as a way
of representing the revolutionary Miracle tuning
discovered by Paul Erlich and Dave Keenan.
This page shows some examples of existing
scales adapted to this new notation that's
ideally suited for 11-limit music.
- Temperamental information
- A page each on meantone,
miracle,
schismic and
diaschismic temperament.
- 7 plus 3 scales
- These are really cool, and I'll try and get some
MIDI examples to demonstrate how cool,
but probably won't.
- My schismic fourth tuning
- This is a way of getting a conventional keyboard to play
precise, non-meantone scales. Have a look if you always
thought extended mappings are too difficult.
- My modified instruments
- Write-ups of a refretted guitar and a MIDI keyboard with
a symmetrical layout.
- Intervals in 31 note equal temperament
- A table showing the ratio space interpretation of intervals
now in the extended 11-limit.
And here are some pages on more abstract tuning theory:
- Tuning lattices
- Background information on triangular and tetrahetral lattices.
These are useful in defined scales, and are used in a couple of
the pages above.
Also, an introduction to
7-limit harmony
- Matrices for beginners
- An introduction to my tuning matrices.
These are useful for mathematical analysis of scales.
Well, maybe not that useful, but great fun nonetheless.
- Notation and Keyboarding
- Stuff about Bosanquet keyboards and the like.
- Anomalous Saturated Suspensions
- Some chords not covered by Partch's o/utonalities.
- Linear temperaments
- A general procedure for defining linear temperaments in
terms of tuning matrices.
- Catalog of linear temperaments
- Big list of everything in the literature and some that aren't.
- Temperament finding program
- Lists temperaments for particular limits, following ideas in the
matrix links above.
A more advanced program finds
temperaments from unison vectors.
- Equal temperaments
- And some stuff about ETs and matrices.
- Maximal evenness proofs
- Proofs of some fairly obvious properties about maximally
even scales
- My MOS applet
- This is an applet for doing calculations relating to MOS scales.
There's not point going there if you can't run Java.
- Unconstrained waffle
- A supplement to my introduction to alternative
tunings
