fretless guitar tuned to 7-limit just intonation – practice session

Sunday, December 28th, 2014

A video of me playing my DIY fretless guitar. It is from October of 2012 but it seems it didn’t make an appearance on my blog when I checked after I ran into the video while clean up my hard drive.

you may have a better experience by viewing on youtube or you can grab just the audio

tuning
C = 1/1, G = 3/2, ~Bb = 7/4, D* = 9/8 + 2/1, G = 3/2 + 2/1, C** = 2/1 + 2/1
* error one in video credits: A is actually D
** error two in video credits: C is actually 2 octaves up, not three

For those wanting to try this – go to your local guitar retailer and pick up a used Fender Squier and loosen the strings until you can push them aside (or cut them and plan on putting on a new set). The with nips gently, but firmly pull out each fret. Then use plastic wood to back fill the fret slots. Wait until the plastic dries and then lightly sand with 400 grit paper to remove the excess plastic. Be careful not to ruin the fretboard by sanding so much you create an uneven fret board whech will lead to buzz. Restring, reduce your action and play! – the plastic will show you where the frets used to be – a nice point of reference.

Mavel Woo Chromatica
This is a short study using a new tuning from a family of tunings Gene Ward Smith recently developed. It is a very chromatic improvisation that just touches what this tuning can do. I intended to visit it with a through composed piece – there is a lot I heard in here that I think has potential despite the cliche nature of this brief study. Truth in advertizing – I edited this and sped it up to keep it interesting.

Gene Smith: Here’s a scale which wins the total 11-limit dyad counts running away:

Ives in 7 limit JI – #68 Ilmenau Over All the Treetops

Saturday, May 3rd, 2014

Looking_over_the_tree_tops_-_geograph.org.uk_-_569960

Ilmenau Over All the Treetops is an adaptation of Ives’s setting of Goethe’s poem dated from 1902 in 7-limit JI. The vocal line is carried by a bassoon and the accompaniment is a combination of Soniccouture’s english theorbo and psaltery. The piece was transposed from E to C to take advantage of the xenharmonium retuning script, also from Soniccouture.

Judas Iscariot Recants His Betrayal (Electric Piano in JI, Harmonic Series and Carlos Gamma)

Monday, April 7th, 2014

The-Last-Supper-large

Judas Iscariot Recants His Betrayal exclusively uses Sonic Couture’s EP73 Deconstructed and is an ambient leaning piece performed live. The piece uses 3 simultaneous tunings, 7 limit JI, Carlos Gamma, and unoctave reduced harmonic series and five EP73 sample sets (normal, mallet, bowed, plucked, and effects). The retuning was accomplished with Sonic Couture’s Xenharmonium script.

For Aeolian Harp, String Orchestra, and Piano is a semi-aleatoric composition that uses a wind played aeolian harp to determine the score for the string orchestra and piano, both of which are tuning to 7 limit just intonation centered on C via pitch determination software.

A Panegyric for Saint Philogonius (in 7 Limit JI for Tape Choir, Filtered Aeolian Harp, Bass drum, and Cymbal)

Many thanks to Dan Powell of Soniccouture who assembled my harmonic filtered aeolian harp samples into a Kontakt instrument that played harmonics 0 => 20 based on velocity. And also thanks to Soniccouture for the Tape Choir and the 7 Limit JI tuning script.

A subwoofer would be a good idea with this one. Or very good ear phones.

Moving With an Incompetent Stagger

Moving With an Incompetent Stagger is a reference to how rough my improvisation is as I continue to acclimate to my 17 equal piano layout. Hitting the right black key can be tricky with them next to each other. However, the tuning did (and still does) deserve further exploration. See the previous post for the scala format of the tuning.
