Septimus dances to remember Mars : Tasmanian Sonata 7

by Ron Nagorcka (2016)

Work Overview

I have been experimenting for some time with ways to write music which explores harmonies based on the 7th harmonic (using the so-called septimal intervals.) There are no septimal intervals on a normal (equally tempered) keyboard so this piece (as well as Tasmanian Sonatas 5 & 6) requires the retuning of 4 octaves of a harpsichord or one 8 ft. rank of organ pipes. This peculiar tuning means that the composer's options are limited to certain harmonies, but these are fascinating enough to have inspired several compositions. As this piece does not use the organ pedal board, it could also be played on a correctly tuned electronic keyboard.

Work Details

Year: 2016

Instrumentation: Pipe organ with one 8 ft rank tuned as instructed (or specially tuned electronic keyboard), clarinet in Bb, double bass and didjeridu (C). The didjeridu player will need to read music. A conductor will also probably be necessary.

Duration: 7 min.

Difficulty: Advanced — 11/8 time

Dedication note: Dedicated to the memory of harpsichord builder Mars Macmillan

First performance: by David Scott Hamnes, Ron Nagorcka, Dan Robinson, Karlin Greenstreet Love at All New Nagorcka (City Baptist Church (Launceston)) on 27 Jan 2018
