How can I get the same “Piano Riff” tone that is on my IPhone onto my IPad

The piano riff is already on there. Just go to the sounds, ringtone, and scroll down to classic. Look around, and there you will find it.

I told you this, and you didn’t listen

(◐‿◑). You’re welcome. Have a great day. (Face from Chinese keyboard traditional).

If the “piano riff” was purchased and downloaded from the Apple Tones Store, you’ll be able to download it to your other devices at no cost:

Settings > Sounds > Ringtone > Download All Purchased Tones

If downloaded from elsewhere, you’ll need to identify the source. Perhaps you transferred the tone using iTunes - from your PC or Mac?

If it was bought on iPhone iTunes Store, all you have to do is go to(I go into clock app) and select the alarm/timer sound thing, and press “download all purchased tones” and enter your password(if you have one) to get it. You could also go into settings > sounds > Ringtone(or whatever sound option there is) and press download all purchased tones(this method it said by LotusPilot).

Tones cannot be directly transferred between devices.

A possible option to explore is to use a suitable third-party application on your PC or Mac computer. One potential option to recovering the Piano Riff tone is iMazing:

Edit

It appears that the Piano Riff is a native tone - and can be selected from iPad settings:

Settings > Sounds > Ringtone > Classic > Piano Riff
