I'm 27, and haven't played since when I was in my sophomore year of college. I got my flutes out of storage recently as my interest was randomly jump started again.

Not to be full of myself, but I wasn't a half bad flute player in high school (I didn't play in college.) Where would you suggest as a starting point to get my skills back up? Just buying technique books, and practicing? Getting a private tutor again or what? Also, I don't know if it'd would be just for my own personal satisfaction & as a hobby or what. Are community orchestras worth the effort or...?

Sorry if this was a lot of questions. TIA

I would suggest that you start by answering the question what sort of music do you like playing and with whom? Also if your instrument has been stored for a while it may need serving if you have difficulty playing notes - especially low ones.

Well, I pulled it out today & I was okay on range (from low C to high C [3 octaves.]) I'm just used to playing pretty much anything and everything that's put in front of me. I used to play for my church, and used to play in middle school and high school band (both marching and concert.)

You should try a community band when you feel up to it. They aren't all good, but they do definitely supplement your private playing.

Sometimes the music is better than the people, sometimes the people are better than the music.

You'll find a good list of community bands here:

Find a band or two close to you and jot them down, then click the link at the top and find them in the full contacts section.

New people showing up for a few rehearsals and not coming back isn't unusual, so don't be afraid to sample them for a short test run and give yourself plenty of time. Community bands can be a lifetime thing
