Learning Instruments of Classical Music: From Easiest to Hardest

1. Timpani
2. Flute
3. Double bass
4. Cello
5. Trumpet
6. Oboe
7. Viola
8. Harp
9. Piano
10. Violin

Timpani, or pretty much any sort of percussion instrument used in classical would be the easiest to learn since it does not require that much practice or skill. Pretty much anyone can be taught how to play timpani without a problem.

I put cello at number 4 because it can be easy for some people with more of a musical background. For others, it may not be as easy to learn how to play the cello.

I put trumpet in the middle because it requires more practice. In order to play the trumpet, you must know how to buzz your lips correctly and know how much air to blow in and how to position your lips. 

I placed piano as a harder instrument because it requires coordination and lots of practice. I think that piano is a harder instrument because you need to know how to play with both of your hands at the same time which can be difficult.
