First let me say hello all since this is my first post on this forum!
I started playing the cello just two months ago. Prior to that I had never played a string instrument and only did 'some' piano but on my own, with no teacher so...I think it'd be a long looong time till I can say "hmm yes, I play the cello"

Nevertheless I'm happy as my teacher says I'm improving at a very good pace (that's why I chose her!)
Let's say that due to poor economic resources I had to buy a cheap cello...a bertarnd one that nevertheless its name is from China I think, it doesn't sounds bad (to my taste) the only problem it had is that the strings where too high from the fingerboard and had to carry to a luthier to lower down the bridge and change the strings for some better ones.
As for why I chose the cello, it's simple: I love its sound!! I love too to hear to violins, violas or double bass instruments but to me the cello seems sometimes to 'speak'

and it doesn't weight too much, being hollow as some have said its very light (I carry it on a soft case).
It's true it usually plays the bass parts but having a wide pitch range, if you listen with care you'll see that now and then it leaves the bass section and 'jumps' to higher levels (just listen to the quartet, quintet or sextet Boccherini pieces) and that's what I like from it, that can carry the melodies from the lower registers to higher ones, or vice-versa.
I think there are some cello solos playing on its high register; here are two or three I know of:
-dance of the elves, from David Popper -(if you can play it!)
-the swan, from the carnival of animals (Saint-Saëns), or his Allegro appassionato for cello (Op 43)
-or 'In the mood for love' soundtrack theme: Yumeji's Theme
