The Modal Dances can be considered 'a collection of seven short pieces for wind trio', and as such any of the movements, or indeed groups of movements, may be used as independent interludes or short suits unto themselves.

Locrian

Beginning with the idea of this mode being 'of the devil', according to Christian authorities in the Middle Ages, I intended this movement to be a kind of aggressive devil's dance, however, true to the rebelliousness of the mythological character depicted, it soon moved beyond these restrictions into a short piece that dictated itself. Staying with the idea of golden ratios, which are very attractive to me and I find fascinating, I decided to use them heavily throughout to compose this piece, but in different ways to ones used in Aeolian. The opening dance-like figure of the flute was the source used to create a kind of metrical canon for the other parts, but instead of having simple relationships between the parts, I used golden relationships which made it more interesting. The three-eight version of the flute became a five-eight version on the clarinet, and an eight-eight version on the bassoon, when it then became a thirteen-eight version on the flute, and so on. Due to the fact that these relationships are not symmetrical, I worked out the golden proportions of the time signatures and determined where stress-points should occur, and how rhythms should be translated. The simple three stress-points in the three-eight become beats one, three and four in the five-eight, and one, four and six in the eight-eight. After the first section ends I then moved into territory that borrows from techniques discovered and used by Danish composer Per Nørgård. His infinity series was the basis of the second section, with the form of the section dictated by a graph of golden ratio. Each bar (the length of which is a number in the Fibonacci series, e.g. 1,2,3,5,8) is then split in two, with rounded-off versions of the golden ratio (in the case of 8/8, three and five beats, in the case of 3/8, one and two beats). At any point in time one instrument is carrying the melody determined by the infinity series, with the other instruments playing specific notes from the series on different 'wavelengths'. This section then leads into the penultimate section, which uses phasing techniques, with the length of each element being a number from the Fibonacci series, in this case three, five and eight. This then leads back into the opening section of the piece as a finale. I am extremely happy with how well this final movement turned out –- it has an aggressive edge, but I soon found it addictive to listen to.

Which method of viewing music should I use?

Score Exchange has two methods to display previews of music: seView which uses regular html and javascipt and the Scorch plug-in from Avid which needs to be downloaded and installed onto your computer. Both have advantages and disadvantages:

seView

seView, is the most compatible option. You should be able to view music on all modern web browsers including most mobile devices. Even if your device does not support javascript you should still be able to preview at least page one of the music.

You do not need to install any additional software to use seView.

Scorch

Scorch is a free plug-in from Avid for displaying and printing music. It can also play the music that you're seeing. As modern web browsers are updated, Scorch is no longer compatible with many browsers. Scorch has never been compatible with mobile devices and some web browsers on Mac computers.

If your web browser does not install Scorch automatically, you can click here to download and install scorch manually.
