David Anderson is a freelance horn player, teacher, and coffee fanatic. He began playing 15 years ago when he found a WWII era trumpet in his grandfather's attic. When not playing or teaching, you can find him in Baltimore gardening and drinking tea with his fiancée and two cats.
Less is more. David’s approach to music stems from the Pareto Principle, or 80:20 rule, which states that 80% or results come from 20% of the work. By focussing only on musical ideas it is possible to achieve excellent technique and sound. If it sounds good, it is good. 
David has appeared in performances with the Lancaster Symphony, Fairfax Symphony, Maryland Choral Society, Manassass Ballet Theater Orchestra, American Festival Pops Orchestra and the McClean Orchestra. David has been working with horn and trumpet players for over a decade and is a graduate of The Peabody Conservatory and George Mason University.
