Songs with satisfying key changes: classic J-POP and Japanese tracks where the mood and impression shift naturally

There’s a technique called “modulation” that’s used when you want to dramatically change a song’s scene or mood partway through.

If we were to explain modulation in depth, it would be enough to fill an entire music theory book, so I’ll skip the details here.

The most common pattern is raising the key for the final chorus to heighten the excitement.

There are also songs that, for example, modulate only in the pre-chorus to catch the listener off guard, as well as songs that skillfully modulate repeatedly while still sounding natural, using subtle modulation techniques.

This time, I’ve picked out a few songs where the modulations feel particularly pleasing or are especially well crafted.

If this article sparks your interest in modulation, please explore further by searching online.

Understanding how songs are put together will surely open up a whole new way to enjoy music!
