This Prelude in 18ET comes from a challenge on the microtonal tuning list to write something in the whole tone scale that didn’t sound like Debussy or Satie. This prelude has decidedly Debussian whole tone passages. All 3 whole tone scales are used. Realized through Pianoteq 3.0, M-audio Keystation 88es
(The first response was a jazz-fusion piece called The Good Boundless that used 12ET – i.e. normal tuning)
My experience with 18ET was that the tuning was familiar and different at the same time. It was fairly easy to handle with a regular keyboard and the mental mapping of every third note being a whole step was easy to remember. As a result I was able to achieve reasonable melodic dexterity and performance speed. I plan to revisit 18ET in the future. Presently I’m working through a backlog of more pedestrian pop/rock music. Also I’m waiting with impatience on the imminent arrival of Garritan Jazz and Big Band sample set that uses the new Aria player – and thus can be programed to use microtonal tunings! That will be a great addition.
