closet musician 

Closet musicians are people who typically play with their instrument(s) of choice by themselves in their room. Don't usually like to perform in front of people and can vary in level of skill.

Nah, I'm somewhat of a closet musician.

Musician Standard Time (MST) 

The time that all musicians keep to that make them function on a different timezone than other people : dinner at two am (after their gigs) go to bed at three am wake up after noon and have lunch at four pm. Repeat cycle.

The timezone that Musician WAGs have to adapt to in order to ever be able to spend some time with their boyfriends.

Best Friend: So why were you still online at two am?
Musician WAG: Oh, I was waiting for John to come over, you know how he is with his Musician Standard Time (MST)

Musician: Baby, I'll call you tonight ok?
Girl: Normal time or MST?

Musician Delusion 

When a musician or band has an over inflated sense of talent. Fan base usually consists of family and friends whom are obligated to support them.

"I'd rather listen to stray cats in heat than one more minute of this crap, these guys have musician delusion."

"No dude, I'm sure that you'll be discovered in this midwestern dive bar, (under his breath as friend walks away) wow he's totally got musician delusion!"

Musician’s Syndrome 

The effect caused by spending large amounts of time with your instrument/vocal part causing the instrument/parts personality to take over. For example, trumpet players become more self-centered and egocentric, whereas cellists become perfectionists, and the people singing the baritone part mellow out. This can be achieved in varying degrees, but begins to show up the moment someone gets an instrument or vocal part.

Dude, what happened to Todd? He used to be so hyperactive before he joined choir.

Don't worry, he's probably just be suffering from Musician’s Syndrome.

COVID musicians

Musicians who have sprung up during the COVID Pandemic due to having more time at home to learn an instrument.

I’ve bought two ukuleles and a Yamaha keyboard so far; clearly I’ve joined the ranks of the COVID musicians who’ve sprung up all over the world over the last few months!
