Hi there, I have been in your shoe before. Thinking of whether do take violin or flute as a second instrument. I played flute for few months before in my school band, but I have great difficulty adjusting my breathing technique. Then, to buy a flute it is more expensive than to buy a violin (both quite economical ones). Then, another thing I am thinking of is that, orchestra normally requires more violin players than flute players:) So, in the end I took up violin, even though I don't like the sound it produces at first, but now I loved it! True, each instrument has it's own difficulty. But the main thing is: practice makes perfect!
In my opinion, violin is hard to learn for the first few months, after you have get the hold of it, it should be easier. As for flute, the notes are quite easy to learn, but not so for the breathing part (or maybe I am not gifted to play any wind instrument

)
