The answer is

violin

because I purchased one just over a week ago and have had one lesson already. I’ve wanted to play violin for a fairly long time. My friend in high school had one and I would tinker with it whenever I could. I play piano (sadly my keyboard is in the states, I don’t want it to break if I ship it), I played trumpet for 6 or 7 years when I was little, and I also play guitar. So we’re adding violin to the repertoire. I’m having a lot of fun with it, even just a couple of weeks in. Here’s a video of a talented pianist for you, Jon Schmidt. He arranged this song from two pop songs for his daughter. I can’t embed the video here but just click this link.
