To buy or not to buy?

The other day I had the opportunity to work with some Music Education Majors in their Brass Techniques class. While I was mostly demonstrating the natural horn, and how understanding period instruments can help understand the modern instrument, I was asked about modern horns and what to recommend to new students to buy.  I thought it was a great question for discussion, because the answer isn't always black and white.
When I started playing in 7th and 8th grade, I took to it quickly, and when I started high school and new I was starting the local youth orchestra, I thought it was time to buy a horn. At our Middle School, we only had single horns, and when the local music store asked if I wanted a single or a double,  I said single - probably mostly because of the $2000 difference, not to mention I didn't really know what the other half of the horn did! But, September rolled around, and within 2 weeks I outgrew my brand new King F horn.... My solution was to practice on it at home, and play the double horns at school (I still played on my single my first year in orchestra, because it was so shiny and pretty to my naive self!) While playing on the F horn obviously has its benefits, it was undermined by my constantly changing fingerings and frustration with all the changes needed to play on the double when I got to class.
Needless to say, by Grade 12 I was ready for an upgrade had enough saved to buy myself a shiny new Yamaha 667.  But would I do it the same way again? Probably not.  I think both times I bought instruments were inappropriate choices (until I found my Paxman in about 2006, and have loved it ever since.)  If you have a student or are a student that has access to horns at your school, use them whenever possible.  My teachers were even willing to lend them out over the summer, and if you have standing rehearsals, they will try to accommodate you.  If you are in Middle School, a single horn is a great place to start. But always keep in mind, it is just a starter instrument, and it is more out of size and convenience to begin with the F horn.  Renting is always a great possibility if you aren't sure how long-term you will need the instruIf you choose to buy, without a doubt buy a double horn, even if it means you have to wait a couple years to get there.  Chances are if you are talented and plan to continue on, by the time you get to University, your playing will have changed significantly that you will probably have different needs, and can get that custom horn  that you've had your eyes on. And whatever you do, TALK TO YOUR TEACHER! They can help you find the right instrument for you at that moment, and what you will grow in to if you are in a transitory state.  And don't just buy new or without trying the instrument for an extended period of time.  Finally, don't be afraid of doing a little reading - this is a big investment! You wouldn't buy a car without checking it out, talking to other drivers, and confirming reviews, would you?  So stay informed, think about the length of time you will play that instrument, and the potential of resale.  Happy horn hunting!
