do you have the 19-tone fretting measurement on a standard Fender scale? am planning to do that to a future guitar project, thanks!

@xelalien

hey look up EMI fret calculator or fretfind and they will give you measurements for any equal temperament and scale length. i believe fender strats are 25.5" (648mm)

Is there some mathematical reason why subminor and and supermajor intervals sound "bad" or is it simply because we've been trained to only look for traditional 12-tone intervals and everything else just sounds "out of tune"

[uethanian]

@MrMss4 search 'harmonic entropy' (haven't trouble posting links in comments)

you can see that subminor 3rds (below 7:6) and supermajor 3rds (between 5:4 and 4:3) are in areas of high dissonance.

math aside, the intervals aren't so bad once they're familiarized. and context is important too; like how a bare tritone sounds dissonant, but in a chord (b and f in G7) it's not bad at all.

I want to write music in alternative tuning systems so bad!!

earlier i thought 19tet wasn't exotic enough for my own taste, but now that i've learned some things about it it's actually really fascinating :D

[uethanian]

@iluvvsmp2 19edo definitely has some microtonal content, you just have to be very deliberate about using it. otherwise you end up in straight meantone, which is what most people associate 19edo with. but there are the other MOS scales like 8/19 and 5/19, and then all the tetrachord variations like the enharmonic. i typically think of 19edo as meantone-with-extensions.

Thanks so much for this video! Sounds great.

[returnofsimple]

have you written any more music than the two songs on your myspace? avidity part 1 sounds pretty sweet. i'd love to hear more.

[psyoptica]

Damn, that sounds awesome. I need a 19 TET guitar!

[TaterGumfries]

One interestin thing you can do with 19 is use deceptive cadences to get to a new key out of the diatonic scale. 

[tkarmakid]

wow, thats really interesting. I never thought about modifying a guitar like this.

[Edmarperlu]

buuuuuuu

[GosseBosma]

Wow this is very cool. And over my head! Are there still seven notes in a mode in 19EDO? Is this related to the ..1-do 2-re 2-mi 1-fa 2-so 2-la 2-ti 1-do

2-re 2-mi 1-fa 2-so/do(repeat 1-2-2-1..) When you add up all of them you get 19 notes before do/so begins again? do you call that 20th note So,Do or Do/So? If the white Db was chopped off a piano and replaced with a piano transposd down a half-step beginning on a black "Eb" reed (or a black "B"??); is this the "layout" of 19 note master-mode?

How would one go about re-fretting one's guitar to 19 tone equal temperament and is it really complicated and risky?

[xelalien]

@uethanian sweet! thanks man!
