That's a funny looking euphonium at the start

[notchieuwu]

this technique probebly only exists cause somoneone was told it can't be done

[lucasm]

I feel bad for the other two Euphonium players that went uncredited

[namenamename]

I love how there's a video exactly like this already, but with a different performance. It's still James Morrison, it's still this piece, there's also a transcription, just a different performance.

The Euphonium is the best kept secret for bands.
“You play the what?”
“…it’s like a tiny tuba”

[lucasprim]

For those wondering, this is mainly achieved through multi-phonics (done when you hum into the horn as you play). He is taking advantage of micro-tonalities in each note to build three note chords

[elijahdoyle]

This channel is beginning to depress me telling me how much I can’t do lmao

[paulkolodner]

This technique was used by Karl Maria von Weber in his concertino for horn and orchestra, written in 1806. He was the one who was ahead of his time.

It doesn't matter that I understand the technique involved, this is friggin' incredible.

[sanderschat]

this looks like the didgeridoo techique.
So you make the base tone with your voice... and you 'sing' the note

[mynameisrosiex]

everybody gangsta until the tuba starts playing chords

[shanekeyes]

My brother used to do this all the time on the tuba! Miss that sound!

"You can't play 3 notes at the same time."
Pianist: "Yes."

[aidanwatson]

The euphonium > everything in life.

[johnrelluf]

I was just about able to do this when I played euphonium, maybe I should pick up playing again. And great vid as always George!

[_codegreen]

holy shit I can barely play one note let alone 3

[NonTwinBrothers]

Fun fact: this video is what inspired me to make the first "You can't play 2 notes at the same time"

[supaF]

It took me a second but as soon as I realized this was Curiosity Show and the presenter was playing so well this video got 10x more badass

[BayleeO-]

But he isn't... He is singing one, playing another, and being in tune creates the third harmonic...

[Placehold]

im curious how hes getting that third note, i know that by using your voice you can play 2 notes at once but is he doing some kind of controlled double buzz to get those top split notes in the chords?
