Can someone help me out and tell me where these three songs (the highlighted ones) are taken from? They've been transcribed for violin, but I would like to listen to the originals if possible.
Not able to nail three totally, but I hope this is enough of an answer to get started with.
Going by the titles in the scans of the music, my inadequate Russian, and help from Google Translate :
Song one is a "Theme from the opera 'The Magic Flute'" by Mozart. A bit vague as a title, but the opera as a whole is worth a listen. Opera is not my thing, but I can listen to "The Magic Flute". Later edit: It's the "Slaves' dance". Link to clip from the opera : https://www.youtube.com/watch?v=PecDdk73ph4&t=1m49s
Song two is "Soldier's March" by R.Schumann. From "Album for the young", a set of piano pieces. Opus 68 #2.
Song three is "Evening Song" ("AbendLied" German) by Mozart.
A few things which Song three is not : there are some youtube performances of something called "Evening song" by Mozart (for Violin duet, the ones I found), but they are not anything like this. Nor is it from "A little Night music" or "Evening thoughts of Laura".
