This has been a fun thread to read!
When I joined BOTB back in 2011, there were not that many multi-instrumentalists active on here. I see that that has changed!
Trying all kinds of different genres, formats, and instruments in BOTB compos has been instrumental (pun intended) in pushing my creativity to new heights over the years! Many of my favorite productions as an artist began as an idea on BOTB. It was a huge part of my life for many years and I will always cherish that! I wish that I had time to hang out here more nowadays.
In order of proficiency, I play these instruments:
Piano/keyboards (since I was 3, and that was 37 years ago!)
Drums (it's my fav instrument although I'm better known for keys)
Bass (I'm arguably better at it than guitar, played 27 years)
Guitar (been playing since I was 11, but have only taken it seriously in certain phases of my life. I'm recently playing a lot of guitar on stage!)
Trumpet (started 29 years ago in middle school band and I still have decent technique, but my lip tires out quickly now due to the fact that I don't play often enough)
Alto and Tenor Saxophone (picked it up in college and took a couple years of lessons...I am good enough to cobble together sax parts on a track, that's about it!)
Yamaha WX11 (MIDI sax)(If I'd got one of these many years ago I might have stuck with practicing saxophone, cuz it's super fun! It makes me sound like I know what I'm doing on sax)
Vibes/Marimba (I got super into mallet percussion in high school and I can still throw down, but my technique is pretty limited)
Recorder (I wouldn't say I'm a serious recorder player but I do enjoy playing it, and have played it on gigs and recordings) (Soprano and Alto are the easiest...I haven't figured out the proper breath control for Tenor and I've never even tried a Bass one!)
Banjo (I'm not good enough to play bluegrass but I'm good enough to play fake old-timey stuff and that's kinda my fav banjo style)
Trombone (many years ago I learned it well enough to teach beginners but I'm super rusty now cuz I rarely play)
...and lots of other random stuff: Talkbox (it is basically an instrument unto itself with its own set of techniques!) Kalimba, Zither, Glockenspiel, Melodica, Mandolin, French horn, Baritone horn, Tongue drum, and pretty much all of the orchestral and Latin percussion instruments.
I'm also pretty serious about vocals! As an instrument I'd say it's up there with keys and drums for me.
When I was much younger it was my dream to be able to play every instrument there is! Once I started doing music for a career I had to choose the ones I was naturally best at. There are only so many hours in a day! Keys/Guitar/Drums/Bass/Vocals are what I have spent the most time on, by far! I miss being able to just spend hours in my home studio messing with random instruments.
Some instruments that I've tried hard to play but just can't play:
Flute (I LOVE the flute but undoubtedly my lip shape doesn't work well on it! I've tried and failed to pick it up many times.)
Violin (I have encountered few instruments that feel so unnatural to hold and play...I tried teaching myself for months out of a book but always sounded horrible! I gave up on it.)
Harmonica - especially chromatic! (I have several harmonicas, even a couple of chromatic ones, but I just can't seem to get the knack for it! I even took a lesson from a world class harmonica player and he taught the techniques really well, but I guess I just didn't spend enough time practicing to get it.)
Pedal Steel Guitar (one of the most complicated and fascinating instruments there is! I find it overwhelming. But if I owned one, I'd learn it!)
Didgeridoo (how in the world does this thing even work?!?)
Accordion (I'm cool with the keys, but lost with the buttons!)
