The ultimate praise of God reaches its peak when accompanied by the powerful, echoing sounds of musical instruments. Identifying the exact ancient instruments used is somewhat uncertain, as different nations and cultures developed their own unique instruments that were not always familiar to scholars elsewhere [אבן עזרא].
The primary approach among commentators is that the initial instrument mentioned refers to cymbals—two copper instruments struck together to produce a sound. These are understood to be cymbals that create a loud, massive sound capable of being heard from a great distance [רש״י, רד״ק, מצודת דוד]. In contrast to this focus on immense volume, another perspective suggests that these are actually small cymbals intended solely for musical accompaniment [ביאור שטיינזלץ].
As the praise continues with a second, resounding blast, opinions differ regarding the specific instrument being played. One approach maintains the theme of cymbals, viewing these as large cymbals that produce a particularly loud and booming sound [ביאור שטיינזלץ]. Another viewpoint identifies these instruments as trumpets, since the underlying concept is one of generating a fierce, blasting noise [מצודת ציון, מאירי].
Beyond the technical and musical details, concluding with this specific blasting sound carries profound spiritual depth. Although the blast is incredibly loud, it actually represents submission and a broken heart. It symbolizes the delicate balance required in serving God: the ability to find joy even in the midst of suffering, combined with the trembling of the heart that characterizes the Jewish New Year. Ultimately, this deep sense of submission leads a person to correct their actions, making them worthy of entering the World to Come and experiencing the resurrection of the dead [אלשיך].
