how do I transfer my music from lap top to new ipad

Any Music/Media content from CD and external sources must be transferred from your PC/Mac using iTunes (or Finder on later Mac computers). “Paid” material from the Apple iTunes service can be simply downloaded to your iPad from Apple iTunes.

The iTunes Application on your PC/Mac maintains an authorised copy your media library - whether this material is loaded from a CD, or downloaded from the Apple iTunes Service - and media derived from this library can be transferred to your iThings. These support pages provide more details:

I hope this information is helpful to you in resolving any issues that you may have.

If using a Windows PC, you need to be using Apple iTunes for Windows to store and save all of your “ripped” music to and them connect your iPad to your PC and transfer/sync your music from iTunes to your iPad.
