Other
Some of his work here on the wiki
RTT
Original work
- Douglas Blumeyer's RTT How-To*
- RTT library in Wolfram Language*
- intro to exterior algebra for RTT*
- temperament addition
- uniform map, integer uniform map*
- simple map*
- unison temperament*
Documentation improvement
- saturation, torsion, contorsion, and defactoring (general audience page, to supplement the existing but more mathematically advanced page)
- defactoring algorithms*
- the pathology of enfactoring*
- defactoring terminology proposal*
- normal lists (revised in collaboration with FloraC to accommodate and enumerate multiple normal forms, and introduced defactored Hermite form)
- matrix echelon forms
- generator size manipulation*
- temperament merging (general audience page covering most of the material on the existing page Meet and join which targets a more mathematically-inclined audience)
- temperament merging across interval bases (a separate general audience page for the remaining material on the existing page Meet and join)
- interval basis (a pragmatic and more basic overview of ideas found on various other pages)
- tuning ranges of regular temperaments
- diamond monotone (worked with original authors to give concept more specific terminology for clarity, and documented)
- diamond tradeoff (worked with original authors to give concept more specific terminology for clarity, and documented)
- eigenmonzo* (did not coin the term, just created the page, including its essentially built-in proposal to rename itself to "unchanged interval")
- mapping to lattice
- val list
- tuning map
- comma basis
- val#Vals vs. maps
- map
- secor*
- grade
- variance
- dimensions, dimensionality, and rank-nullity theorem
- full-rank and rank-deficiency
- linear dependence
- basis
- generators preimage transversal (provided in-depth explanations of algorithms developed by others, supplementing with code implementations and examples)
- preimage
- detempering
- support
- essentially tempered chord (added the diagram)
- harmonic distance
- error
- damage
Suggested improvements
Non-RTT
Original work
- N2D3P9*
- monotonic tunings
- arithmetic tunings
- non-arithmetic monotonic tunings
- edφ
- metallic MOS
- generalized superparticulars
- xenharmonic series
- Gjaeck
- Yer
Improved documentation
- subharmonic series
- acoustic phi
- Maximum variety#Examples testing for MV
- direct approximation (adapted from "patent interval")
