[Trombone-l] When to use what instrumentation

[Mark Mohwinkel]

How do you decide whether or not to use an alto trombone or tenor trombone for the first part in orchestral works.  Some parts are written for "trombone" in alto, tenor and bass clef.  Some are written for alto trombone, tenor trombone, base bone, etc.  But I also know that alto clef doesn't necessarily designate alto trombone.  Don't say ask the principal - that's me.  Also, I don't think the conductor will know for sure (or really care) since it's a very amateur orchestra.  I'd prefer to play the alto clef parts on alto bone (for practice) but I'd just like to know how to figure it out.  How do you decide (if you're the one making that decision)?  Thanks (I lurk a lot, contribute little, learn a ton!).
