Star Spangled Banner in 19ET

based off of a frangrance oil i bought online called Silver Cedar
https://oregontrailsoaps.com/Silver-Cedar-Fragrance-Oil.html
"A very noble scent reminiscent of a majestic cedar tree standing tall and proud in the forest of the Pacific Northwest, cedar trees are used for their intoxicatingly aromatic wood and this this scent is full of luxurious crispy cedar freshness. Soft and lovely, it is not overpowering as some can be, it's just perfect. Soaps white, does not accelerate and dries down to a lovely fragrance. I had fun mixing it with citruses and other fragrances and found it to be unbelievably versatile. I think you will, as well." 

Life Haunted

This is a justly intoned arrangement of J. S. Bach's Prelude and Fugue in C Sharp Major, the third Prelude and Fugue of the 48 Preludes and Fugues, a body of work by Bach which demonstrated that with tempered tunings every major and minor key was usable. It was made using a custom sequencer in Excel+Octave which allowed exact frequencies to be specified.

'Comma Travel' means that local sections of the Prelude and Fugue were specified using simple justly intoned ratios, but the whole piece was stitched together by (from time-to-time) specifying commas, that is, microtonal intervals which make the different sections exactly match up. By altering the baseline frequency dynamically in this way, the whole piece of music suffers from 'comma travel' which is the accumulation of commas in the sharp or flat direction, making the music shift up and down in frequency. However, since there's not much in the way of 'comma travel' music already on the market, I thought this would sound interesting to some people!

A more sophisticated way of making the piece of music stay at the same base frequency would be to normalise the commas by dividing out the comma by a local moving average; this has also been done in two separate tracks uploaded at the same time.

Accumulation of commas, normalised or unnormalised, will be explained further in my second JI maths/music paper - pending! The theme of it is how to take any sheet music and retune it into JI using comma alterations, mainly of 5th and 7th harmonics. However, as always, in this track I've snuk in some 11th and 13th harmonics which you might be able to locate by ear or by examining the code blocks in Github (upload pending as of 9th Nov 2015).

Enjoy!

Bach BWV848 Prelude And Fugue in C Sharp Major - Chip Solo Synth, Justly Intoned, Comma Travel

epic lofi synths aaaaaa i spent way too long producing this

I Pulled The Stems

A preview version of a piece that a friend of mine, Aaron A. Hunt, composed as part of a collection of 24 Preludes & Fugues in odd meters:

The score is available here http://zwillinge.zentral.zone/katalog?en
I'm aware of lots of flaws in this recording (including my performance) and beg your indulgence for this, but I found it was high time to take the next step after all the practising that I had already done: It seemed better to me than to maintain silence.

@uz1kt3k: I hope you forgive that I didn't ask for your permission to use the score cover here beforehand. (meanwhile approved)
