Hey, nice to see you back!
I thought the idea interesting at first - since I play 5-strings, but as time has gone on I keep seeing more players of fretted instrument going fretless, or flush-fretted, which seems just like training tapes on a violin. Plus, the fingerboard of a Violin or Viola is so much shorter than the neck on a guitar or banjo.
You could probably stir up some more interest, maybe show us how great the frets work for you now?
Would LOVE if you post some of your videos in the share or critique headings - OR, join any of the current or past 'Parties' with a video of yourself playing your fretted violins!
How can you play using pythagorean tuning if you have frets installed. Frets would also affect intonation, unless they are completely flat, what you have effectively is a bowed mandolin.
I honestly dont see the point.
A long time ago I tried the stick-on fretboard on a cheapo violin. Intonation was bad. I might have been able to improve the intonation by adjusting the position of the bridge, but it didn’t seem worthwhile. It made more sense to figure out how to play correctly without frets.
And I did have a brief opportunity once to test a fretless bass guitar. It seemed pretty intuitive, I liked it. I didn’t have enough time to get good at it, but for some reason bass guitar intonation seemed easier than violin. Maybe the longer scale made it more accessible -- ??
