To change the tempo, the weight can be moved up or down the pendulum rod. Because there is a second, fixed weight on the opposite side of the pendulum pivot, within the metronome box, this mechanism is also known as a double-weighted pendulum. The metronome's pendulum oscillates back and forth in time, and with each oscillation, a mechanism inside the device emits a clicking sound. Battery-free mechanical metronomes are powered by a spring-wound clockwork escapement.\u003c\/p\u003e\u003ch3\u003eMechanical Wind-up Metronome Description:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eColour: Black\u003c\/li\u003e\n\u003cli\u003eSynthetic casing\u003c\/li\u003e\n\u003cli\u003eWith 5-position on\/off bell. \u003c\/li\u003e\n\u003cli\u003eTempo scale 40-208 bpm.\u003c\/li\u003e\n\u003cli\u003eTempo Tolerance 1%.\u003c\/li\u003e\n\u003cli\u003eIncludes instructions\u003c\/li\u003e\n\u003cli\u003eMade in Chine\u003c\/li\u003e\n\u003cli\u003eDimensions: (mm) : 103 x 118 x 205\u003c\/li\u003e\n\u003cli\u003eWeight : 480 g\u003c\/li\u003e\n\u003cli\u003eOperation without batteries\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Anitom OOD","offers":[{"title":"Default Title","offer_id":54226554028378,"sku":"ECH WSM-330-BK","price":38.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1017\/5810\/7994\/files\/ECH-WSM-330-BK-2-B.png?v=1780584577","url":"https:\/\/anitom.co\/products\/mechanical-wind-up-metronome-pyramid-shape-by-cherub-ech-wsm-330-bk","provider":"Anitom","version":"1.0","type":"link"}
