Musician

Musician is an achievement/trophy in Metro Last Light.

Overview
This achievement is awarded to the player for finding and playing all 17 musical instruments in the game. There are only four types - guitars, accordions, balalaikas (triangle shaped guitar) and pianos. There are a total of 17 musical instruments in the game throughout the levels. All 17 must be played in one playthrough, in level order. If you miss an instrument, you may use level select, but you must then play the game and collect all instruments in that level and all other levels after that one again. You cannot use level select to only play ones you missed, unlike diary pages. Below is a complete list of all 17 instruments.
