App for intonation practice
I have been learning violin for a few weeks now, had one lesson and was taught bow hold, finger positions, and the C major and G major scales. (I do play piano so have music knowledge already). I won't have my next lesson for at least three to four weeks, and I want to practice before then. Right now, I'm using a tuning app to slowly play each scale and watching that for my intonation as I play, but it is a little inconvenient.
Is there any app that can listen to you playing scales and/or sheet music you upload and give you feedback on things like intonation?
EDIT: I don't mind ads but I don't want to have to pay.
Another question while I'm at it, my tuning app for my violin is designed for string by string tuning, but my teacher told me to tune a-string, then a and d, then d and g, then a and e. I think she does it by ear although I'm not sure if she has perfect pitch or not. Either way, I can't, so how can I tune in this way?
