Hello there, and welcome to the world of Tamagotchi's and to here on TamaTalk
Don't worry, the Music Star is pretty straight forward once you get the hang of it.
I'd type up all of the information, but that would be rude considering so many other have, but here, I'll link you to the more important Guide and Character Charts and Instructions, things like that.
Here is a Music Star Guide to the Tama and all it's uses/games:

Here is a Character Growth Chart (the link in the first post) :

Here is just a character chart, showing you what the character look like on your Tama and just listing the girls and boys, similar to a growth chart but just the characters really:

And this is something called the Music Star Project, I've never used it myself but I know that others have found it pretty useful, and there is a large amount of complied information about just the Tama Music Star and nothing else:

I hope that you find these helpful! I did, but if you have anymore question please, feel free to PM me any of your questions, or just post in here again, I can run in and check back later, and I'll be glad to answer and help in anyway that I can.
p.s. when your Tama becomes a Toddler there is a minigame that you play to practice, a lot of people have had trouble, so I made these instructions:

Good luck!
