When I started learning to speak Japanese, my teacher told me to stay fairly monotone. English, she said, is like a song. Japanese? That¡¯s more like a machine gun.

While Japanese may seem rather ¡°flat,¡± listen carefully and you¡¯ll hear some fluctuation thanks to what is known as pitch-accent.

Pitch-accent, known as ¸ßµÍ¥¢¥¯¥»¥ó¥È (k¨­tei akusento) in Japanese, is the term used to describe when a language prominently sounds syllables or words by changing the pitch, rather than the volume. For example, ¤¢¤á (ame) can mean ¡°rain¡± (Óê) or ¡°candy¡± (ï) depending on whether the pitch goes high-low (rain) or low-high (candy). In fact, there are four pitch-accent patterns in Japanese: î^¸ß (atamadaka), which goes high-low; ÖÐ¸ß (nakadaka), which goes low-high-low; β¸ß (odaka), which goes low-high; and ƽ°å (heiban), which means flat. More on these later.
