36 solfeggio tones

The following two musical experiments are based on the above hex-arrangement of solfeggio tonality, something based off of the 81 Lo Shu tones mentioned in a previous post.  These études, if-you-will, are a continuation of my initial compositional explorations with this temperament.

The Rubin Museum of Art

I’m very excited to be performing at the Rubin Museum on Friday, August 5th at 7pm.

This performance will feature new music inspired by Himalayan artwork.  The band will be exploring the theme of impermanence while composing new pieces for improvisation.  It will surely be a special performance, one of which I am honored to present.

Eye In The Sky – a bonus track

There’s a bonus track to Community Immunity; it’s a tune called “Eye In The Sky” and is part of the ‘director’s cut’ if you will.

modern solfeggio tonality

Inspiration:
“If you only knew the magnificence of the 3, 6 and 9, then you would have the key to the universe.”
– Nikola Tesla

Description:
The numbers 3, 6 and 9 have ancient, numerological application.  For example, 3 can symbolize two opposing extremes with a point of balance in between, and the numbers 6 & 9 govern the I-Ching’s Yin-Yang dynamism, but this is only scratching the surface.  If you wish to take the plunge, consider immersing yourself with the Lo Shu tones.

One way of incorporating this idea will be the use of specific frequencies that have a ‘digit sum’ of 3, 6 or 9, just like those in Gregorian ‘solfeggio’ tones:

UT – 396 Hz
RE – 417 Hz
MI – 528 Hz
FA – 639 Hz
SOL – 741 Hz
LA – 852 Hz

Example:
Consider the syllable “FA” which cycles at 639 Hz:  6 + 3 + 9 = 18, and  1 + 8 = 9.
Thus the ‘digit sum’ of 639 is 9.

Here is a scale created with the following set of 81 lo-shu tones as shown in Hz:

111,123,135,147,159,162,174,186,198
219,222,234,246,258,261,273,285,297
318,321,333,345,357,369,372,384,396
417,429,432,444,456,468,471,483,495
516,528,531,543,555,567,579,582,594
615,627,639,642,654,666,678,681,693
714,726,738,741,753,765,777,789,792
813,825,837,849,852,864,876,888,891
912,924,936,948,951,963,975,987,999

The following audio clip represents my first attempt at composing using only pitches from this scale:

Much of melodic expressionism lies in the ‘notes between the notes’ so-to-speak, and this scale is one specific way of exploring such a practice.  Weighing in at a little over three octaves, its intervals resonate with unique harmonic characteristics unheard in 12-tone equal temperament.  These 81 tones are a ‘geometrically-coherent, crystalline structure’ ripe for harvest.  There is much to explore in composition.

The technical how-to:

This scale was fabricated digitally with the help of the software CSE (Custom Scale Editor) which can be used separately or in conjunction with Scala.  If you’re looking to get involved with MIDI microtunings, I recommend to skip the elaborate process of installing Scala and simply use CSE to save time and potential frustration.  CSE is all you need to create and/or perform custom tonalities.  Its author, Aaron Hunt at H-Pi Instruments was hugely helpful in getting this little experiment off the ground.

for cherice

Got a call from frequent collaborator and esteemed choreographer Cherice Barton a few weeks ago when she was in seeking original music to compliment Edith Piaf‘s Non, Je Ne Regrette Rien (translation: No Regrets):

To precede Edith’s song, I composed a piece with a similar yet modern vibe; a piano solo with accompanying brushes on a snare drum:

This is for a solo, modern dance program featuring Lauren Gaul, as choreographed by Cherice and premiered May 13 & 14 at Purchase College.
