New Words and Kanji

I have a new word I've picked up.
It's it's music, ongaku.

音楽
The kanji are sound (on) + music/comfort (gaku).

Take note there's a homophone here, which occurs (very!) often in Japanese.
gaku is also learning, or 学
so gaku ≠ gaku if we're talking 学 and 楽

Keep also in mind that in general, 音読みis for pairs and 訓読み is for individuals.
Why?
alone, 学 is gaku, and
alone, 楽 is raku. gaku is the chinese onyomi for pairs for 楽.
(See Kanji - the Chinese Characters for further explanation.)

I'm hoping to get more words like this lodged in my brain once school is over and I have time... It's going to be sad when it ends, though... I'm going to miss all of my friends...
