Jonathan Casey Film Music Composer

Hello! I'm Jonathan.


"I haven't worked with a more professional,
committed or talented creative individual than Jonathan."
I would be lucky to work with him again."
Director Luke Leslie, Replayhouse

I'm an Irish composer
and I'm happiest when writing music.


Songwriter and Composer

Jonathan composes film music
& writes songs. All day long.

Get in touch. He's probably writing right now.



Jonathan Casey also performs music.

He sings and plays all around the world.
Stops for dinner. Then plays again.

what I do...


I'm happiest when writing music and I'll make you happier. I'll write any music, in any style, for any ensemble that you want and when we're done, I'll go ahead and write some more. 


I am a film score nerd and buff; it's my passion. I always know how to make the right music and I'll make it sound amazing. Too much misspent youth devouring TV, movies and soundtracks has made me an expert in this field. 


I play piano, guitar, ukulele and sing - I do these at a professional session level, performing top level gigs in different roles in different bands.


Clients like it when I arrange and orchestrate their music for orchestra, because I hear unusual possibilities and can take things to new levels.
Just ask De Dannan, MrNorth
& Fusion Family.
