Weeeell, I used to be in the school band from fourth grade to ninth grade. At first, I played the flute. I was absolutely NO good at it. My fingers were too slow, and my flute itself was bad quality. I sounded horrible playing that thing... But I loved it. The flutes got such lovely melodies. I stopped around 8th grade, when I left my flute in the instrument closet and never saw it again. How I wish I remembered to pick it up.
In 8th grade, I started playing the marimba/mallets/xylophone/whateveryouwannacallit. I was decently good at it, because it was essentially a big piano, something I was somewhat familiar with beforehand. My only issue with the mallets was the fact that you had to split your vision in two - one to look at the music itself, and one to keep track of where your mallets are hitting the keys. I never mastered this, and I often ended up memorizing the pieces we were playing. I did really love this instrument, and I wish I could pick it up again.
In 9th grade, I started playing the alto saxophone. Worst year of my life, and I would never return to this instrument if you set me on fire. I was absolutely awful at it, I couldn't play any of the songs I was assigned, and the teacher was so strict and so mean to me. Ruined the instrument for me forever.
I'll be getting an ocarina soon, and I hope it'll come easily to me, since I've played woodwinds in the past. It seems like a generally easy instrument to pick up, as it only has so many buttons and button combinations, unlike the ridiculous saxophone.
