It uses hurdy-gurdy, so an automatic yes.

'Toss A Coin To Your Witcher' has been going around my head for a week lol. 'Tomorrow I'll Leave Blaviken For Good', 'The Time of the Axe and Sword is Now', 'Everytime You Leave' are also great. Haven't had a chance to listen to everything yet though - the soundtrack dropped on spotify just two days ago

Looove the Slavic "white voice" technique you can hear in some songs like link. Makes sense coz the whole thing is set in imaginary Poland lol. But it just suits the medieval setting so well and I adore it. White voice in traditional Slavic songs for context: link, link.

The composers also link for fans, including:
"1. Giona & I personally performed and recorded over 60 instruments in order to create over 8 hours of an exciting original soundtrack. A lot were custom made and crafted specifically for the series.
2. Giona had to learn to play woodwinds for the soundtrack. Him being part Italian, how much swearing and cursing do you think this process entailed?
3. @rodionbelousovofficial recorded the virtuosic oboe solo for Pretty Ballads Hide Bastard Truths. You might notice there's barely any space for him to breathe on the track. This isn't edited. He had to use a circular breathing technique to get the part right."
