Got a new iPad generation 8. Trying to set up a new iTunes account. First time user. Can you help

My husband is a musician and he has recorded music on an old I pad that we want to get put on the new iPad. The problem is with the iTunes account I have on my laptop. I do not want to syn them together because there is a problem with mine and I want him to have a new iTunes account on his new iPad. But we are having trouble trying to get iTunes onto the new iPad which is a generation 8. Can someone help me get iTunes onto this iPad?

Down at the bottom of the iPad there is the music icon. What he has done is record live music through a program on my laptop and they have the iPad connected to the laptop so the music gets loaded onto the iPad that way. It is just the back ground music being recorded. Now when we got the first iPad for the group, another member of the group signed into it, so it was under their name. Then it started acting up so they got another on and everything was just synced over to the new (second) one which was fine at the time. Now that person has left the group and a new person came in. Everything still fine until a couple of months the person who left got an update on their personal iPad and so she put the update through which effected the iPad that was being used by my husband because ours is still in her name. So we bought another iPad (#3) which I put in my husbands name and now we need to transfer somehow the recorded music from iPad (#2) and get it into iPad (#3) without any of her information on iTunes syncing over to the new iPad (3). I hope need to have the music account in my husbands name and you just can’t put iTunes on an iPad like you can a laptop. I was going to try and open an account in his name on my laptop and try to transfer the music to it on my laptop but I am not a tech. I hope this explains it better.
