Tune
Piece Of Music, Song, Melody
counter, independent noun, in compounds
This almost shares the meaning with the kanji. It's essentially the same thing, though when it's alone it refers to a specific piece of music (aka a tune).
The reading is the same as the one you learned with the kanji as well, so you should be able to read it.
その曲の名まえ、何だったっけ。
What was the name of that song?
何かおすすめの曲はありますか？
Are there any songs you would recommend?

He played a tune for us on the piano, but for some reason, the piano sounded like a guitar.
