which one is better could play many or just one musical instrument skillfully??

yes of course, playing more instrument will increase your creativity in music, but masterized in one instrument is also needed to define that you are a great musician

hey guys ive played guitar for 16 years, its practically another limb. i think its important that once you take up an instrument, never to quit. be inspired by many different types of music, and gain experiences from them. the more influences you have, the better creativity you will have writing your own material. Or, you can adapt different sounds/techniques when covering someone elses. ive recently picked up drums, and piano. i would change this for the world. i love being a one-man-band. i have a home studio, and recording songs is my life. but i do sometimes feel by rehearsing piano, and writing a song on it INSTEAD of guitar, does cause you to lag behind. I spent a couple of months where i didnt pick up the guitar, because i was too busy developing my piano playing. my guitar playing suffered for this. i think if you want to be in a band, or a solo musician, the more strings to your bow the better. your influences and experience bounces off others, or indeed pushes you to break the boundaries of what may otherwise be quite a boring song on an acoustic. people who only stick to one instrument though, end up being bloody brilliant at it!

yeah i think we have different mindset about music for me if we could play many musical instrument it will help us so much to make an original music by ourself

that was exactly i did when i was in high school i love to learn and know more and more instrument and it really increase my arrangement skill, so i think "jack of all trade master of none" is still good for me thanks angelic ;)
