It can potentially be used to either seal or unseal the Big Bad. There was a magical ocarina in the thirteenth Dragon Ball Z movie. It's also the way for a pilot to access the powerful Spacetime Convergence Cannon. In Cross Ange, a Ragna-Mail's Golden Super Mode is activated by singing certain songs. Later, Professor Inukai uses Yui's singing as a part of his battle strategy against the Big Bad, who is weak against certain sounds, and Haruna returns the favor to Yui by singing the song to her when she's about to lose the battle against Grosser, giving Yui her strength back so she can keep on fighting. it becomes a plot point later, when Yui's "I Know You Are in There Somewhere" Fight speech to a Brainwashed and Crazy Haruna includes her singing the same song instead of fighting her, breaking through Haruna's brainwashing an reverting her back to who she usually is. In Corrector Yui, Yui and her friends Haruna, Reiko and Akiko were rehearsing a song for their School Festival.
In the manga, all of the Apostles have the ability to control the Astral Line through music-all of them are shown singing, except for Joshua, who channels his powers by playing an Ominous Pipe Organ instead.

It's beautiful, it's heart-breaking, and it transforms innocent people into horrible bloodthirsty bat-demon-things.
Kahono's Song Magic in Black Clover works through songs, letting her sing a sleep-inducing lullaby, relieve fatigue, and even produce shockwaves and air barriers. In the Ah! My Goddess manga and movie, particularly powerful and/or complex magical effects can be accomplished through singing (such as the reversal of a spell with both heavenly and demonic components and the recreation of the The World Tree), often but not always in combination with Hermetic Magic.
