Seventeen’s 24H is already the group’s fourth original Japanese single, continuing to represent their successful push into international markets. It comes on the heels of March’s Fallin’ Flower, and uses that track’s energy as a jumping off point. But, 24H pushes us in even stronger directions. Its willingness to explore is appreciated.
Composed by the usual team of Woozi and Bumzu, 24H borrows from many of their preferred sounds but ties everything together in a taut, forward-moving package. Its greatest success lies in its ability to shift and grow as it goes on. Rather than circle back to the same elements over and over, 24H unfolds like a musical story. This is in spite of a melody that’s really quite repetitive. However, the track’s arrangement spotlights this melody in different ways, tweaking the energy for a dynamic – but never jarring – journey.
Opening with insistent kick and gentle acoustic guitar, 24H’s verse snowballs as more instrumental elements are brought in. It’s a classic approach, but one that’s rarely unsuccessful. From here, the song’s chorus enlists chugging guitar to lend the refrain a great sense of drive. Its second verse holds on to some of this rhythm, but it’s not until we reach the bridge that 24H reveals its trump card. We move through an aggressive, chanted segment to a brief moment of open space before the chorus returns with even more rhythmic bite. It’s a great way to tease out the strengths of both the melody and performances. For me, this is easily Seventeen’s strongest Japanese single since Call Call Call.
