David Ryan: Difference between revisions

David Ryan is a mathematician, music theorist and composer based in the UK.

His main musical interest is working with and exploring [[Just_intonation|Just Intonation]] (JI). He developed [[Rational_Comma_Notation_(RCN)|Rational Comma Notation (RCN)]] in order to provide a link between the mathematical domain of rational numbered frequencies and the musical domain of understanding music better through its notations.

Although RCN is not the only [[Notation|notation]] system which exists for free-JI, it has some desirable properties:

<ul><li>being able to use traditional note names like in [https://en.wikipedia.org/wiki/Scientific_pitch_notation Scientific Pitch Notation], e.g. C4, G5, F#2, Bb7</li><li>higher prime commas describe microtonal alterations, e.g. [5] [7] [257]</li><li>prime commas can be combined into a single rational comma for each notation, e.g. [35] = [5] * [7], [11/13] = [11]/[13]</li><li>it uses algorithms to assign all higher prime commas</li><li>RCN has a version for each algorithm (the author recommends a particular algorithm)</li></ul>
