How do I get iTunes on my iPad

There is no app named "iTunes" on iPads or iPhones. There is an "iTunes Store" app, an "iTunes U" app and a "Music" app.

If you are looking for one of those and they are not on a Home screen, go to the App Library (swipe left past your last home screen). From there you can touch and hold an app and slide it left back to the home screen.

Also note the Search window at the top of the App Library.

If they are not in the App Library, see the following from Delete built-in Apple apps from the Home Screen on your iOS 14 or later or iPadOS device or Apple Watch - Apple Support

Restore a built-in app that you deleted

1. On your iOS or iPadOS device, go to the App Store.
2. Search for the app. Make sure that you use the exact name of the app.
3. Tap the Redownload button .
4. Wait for the app to restore, then open it from your Home Screen.
