(Cover) - EN Showbiz - Justin Bieber is eager to master bass guitar as he thinks it would be "cool".

The 17-year-old R&B sensation is a gifted instrumentalist, and already plays the piano, drums, guitar, and trumpet.

Justin doesn't always get the chance to show off his music-playing skills though, as many of his tracks require him to concentrate on his silky vocals and fast-paced dance routines, and this is something he does worry about.

"People think I am a product and sort of a money machine, but it's not true. I am an artist. I've been with music all my life," he told the British edition of OK! magazine.

"I've been playing all sorts of instruments. It'd be cool to play bass one day."

Justin also discussed the pitfalls of being successful at such a young age. The star is adamant he will make errors along his pop journey, but feels confident his loved ones will always be on hand to offer support.

"Of course, I am going to make mistakes. I am just a normal guy, but I think I have a good head on my shoulders. I've got my family around to keep me humble," he smiled.

"I don't need people feeding my ego and saying how wonderful I am or to sing the whole 24 hours. I need to be true to myself." (C) Cover Media
