覚え方のコツ Memory Tip
metro- を「測る」、-nome を「規則」と結び付け、「拍を規則正しく測る装置」と覚える。set the metronome to 80 BPM、practice with a metronome、keep a steady beat が典型表現。時計そのものではなく、音楽練習で一定間隔のクリックや動きを示す器具である。
Break metronome into the Greek-based ideas metron, “measure,” and nomos, “rule”: it is a device that gives a measured rule for musical time. Picture a pianist practicing while the metronome clicks evenly or a drummer setting it to a slower number of beats per minute. Common patterns are practice with a metronome, set the metronome to 80 BPM, and keep a steady beat. Unlike a clock, it is not mainly telling the time of day; it supplies evenly spaced beats so that a musician can learn or check a chosen tempo.

metronome の語源・成り立ち Etymology
ギリシャ語 metron（測る）+ nomos（法則）から。「リズムを測る道具」が原義。metro- は metric（メートル法）、-nome は astronomy（天文学）の -nomy と同根。音楽の拍子を正確に刻む装置という意味が語源そのまま残っている。
Metronome entered English through a modern European formation based on Greek metron, “measure,” and nomos, “law, rule, or established practice.” The name was created for an instrument that regulates musical time by marking equal intervals. Its elements therefore describe the device’s function rather directly: it provides a measured rule for tempo. The word became established in the nineteenth century as mechanical metronomes were developed and promoted for musical practice and tempo indication.
