In order of starting instruments I played:
Trumpet>Violin>Guitar>Baritone Horn>Piano>Double Bass>Tuba>Bass Guitar>Mandolin>Chapman Stick
Now this iwas not as schizophrenic as it looked. I played trumpet in 6th grade band, and switched to baritone in 7th grade. They made me switch to tuba for marching band in 9th grade.
My sister started violin when I started trumpet. I made the mistake of picking up her violin while she was out of the room, and an hour later, I was better on it than she was. So Mom made me take orchestra in 7th grade. Later in the year the teacher let me switch to DB. But The school I moved to wouldn't let you be in orchestra AND band. So I quit Orchestra.
My grampa was an old jazz cat. ( He had played western swing with the Lightcrust Doughboys.) He was a guitar player and said he would give me pointers on guitar. I played guitar for a couple of years. But the DB and tuba had taught me to listen for the low end. So in 9th grade, I saved my lich money for about seven months and bought my first bass guitar. I haven't looked back.
Sometimes I would get interested in a different sound and learn a new instrument to have that sound or to better understand the other instruments I already played. Sometimes it worked (keys, mandolin) sometimes it didn't (Chapman Stick)
