the viola is tuned like a bass guitar, upside down.
G, D, A, E?
the progression fretting is; using G,
g a b c d(key of next string) e f a
d e f g a
a....
e....
its like, on a guitar, first fret, third, fourth (tune next with), the flat and sharp ranges, you vibrato in and out of.
the bow, buy a decent instrument, but better bow and strings.
id start with d'adorra "Helio core", get ready to study the strings and bows. different strings produce a different sound, and warmth/coldness, that is to compliment your instruments construction & sound, and your style.
tunning takes a while, dont be too nervous with those expensive strings

watch a pro do it, or get a feel for it, then find a suitable instructor.
depending on where you live,,, my experience was zero viola players...!
i found a celtic fiddle instructor, he said call him back, the tunning and sound is very different, the names will make sense once you hit a fat G D chord

ive had both, and stuck with the voila.
using just enough resin, a decent climate, drop tunning when putting away, and a mute are good ideas.
ive played guitar, acoustic a long time, and have thick calluses, but holy shit... once you fly through a few hours, its easy to make your fingers bleed or not want to play for a couple of days.
having a lintless cloth to rub her and the strings down before and after, is rewarding..! they actually need to warm up also, youll notice.
heheh
