Taking on more instruments allows for a better understanding of music. I find myself applying my violin knowledge to my piano playing quite a bit.
Thanks for the replies - this is some good information. I definitely agree with the argument that playing more instruments helps one as a musician. As for time, I realize that one will be the priority and I'll just have to see how it plays out as I get back into piano. I have a full time job, but I can practice music for about 3 hours per day. For me, music is a serious hobby - I regret not pursuing it seriously at a younger age, but I was not ready for it then. I would like to get more involved over time and teach someday.Thanks again for the advice. Now, I have to decide how short I can have my nails for piano and CG.
