Is it natural for Equestrian ponies to habitually break into song randomly?

[HorsesandMOARGaloar 300]

I am studying the psychology of Equestrian ponies, and I wonder if it is some form of instinct for some of them to suddenly create a song in any random moment.

 

Is this a confirmed instinct/habit?

Psychologically it appears that is a "happy mode" that increases the chance for a spontaneous outburst, so one must assume that, They instinctively break into song to celebrate and tell everyone their happy

I once posited a headcanon that "ponies breaking into song" is actually caused by a magically-affected gene which was inherited to common ponies many generations ago by a milkmaid who would only speak in song. Many ponies have it to a minor degree, but it is a dominant trait exhibited in Pinkie Pie.

Maybe it's something really deep, maybe they just like singing. Does it really need an explanation?

but they sing when sad or scared, too.

but they sing when sad or scared, too.

I would agree and might change my point to: when emotionally effected by happiness or other emotions

Actually, crowdsinging seems to be a pony thing.

[Red Cedar 1,406]

All ponies have an innate sense of musical ability that even the most shy, unassuming and tone-deaf pony can burst into a fully-realized song at the drop of a hat. In fact, this is so heavily ingrained in them that it activates a psychic link to nearby ponies that allows them to sing backup perfectly.

 

Unfortunately, this is not always convenient:

Don't laugh. Qualified psychologists, as an exercize (or an April Fool's Day joke), have done a thesis on Bruce Wayne.

I would say 'why not?' don't we all in the real world, at one time or another, sing in our heads, or outloud, or hum or whistle a song we like? It's random but for some of us it helps us get through the day.

I suspect its contagious like yawning or laughter, for them but much stronger. But I suspect there are some ponies, like the equestrian games representative, who do not sing that often.

 

So it could just be the friendlier areas do so, or because they are the elements of harmony, but who knows which is the exception to the rule.

If ponies bursting into song at the drop of a hat is normal, that's the real magic.

I think it's in pony nature to sing when a song pops into their head. Singing is like breathing for them, It's a habit they can't break. That's just my theory.

As with many PG-13 children's based creatures, since the time of Walt Disney, it has been their credo to express themselves through the art of song and drama, even as they writhe in agony.

 

As a professional assassin also told me, its the best time to sneak in a well placed headshot with high success and minimal consequence.

Well, most of the songs in the show aren't really acted, I guess. I think you could say that the ponies don't even know they're singing, it's just part of the story.
