They're probably thinking about when you blow across the top of a bottle. In that case more water is a higher pitch. This actually really surprised me.

@cz1822

When blowing across the top of the glass, moving air is causing vibrations to produce sound. Since the air is the cause of the sound, less air (more water) = higher pitch.
When striking the glass directly, the air is not involved in the process. The water acts as a medium to amplify the sound of the vibrating glass. Since the water is causing this sound, more water = lower sound.
Basically, the larger the medium is, the lower the sound. Since water is the medium in this case, more water creates a lower sound.

Bruh why don't they literally just try it themselves

I love that this is just a 10 second demo instead of a long clickbaity emotional video

@davidgriffin79

Pitch is a function of stiffness and mass: that is, pitch is proportional to stiffness and inversely proportional to mass.  The proportionality function depends on the system.  You added more mass to the glass thus lowering its fundamental resonant frequency.

Ya boi doin music magic โœจ

Science magic in music

@walterlay8725

It's because when you're hitting a glass of water. The sound is transferred through the water. But when you're blowing on the top of a bottle, it's transferred through the air because that's the chamber where the sound is Amplified.

Dude, they're probably new to your channel. Old timers would know

Haha, to those who said that. "It's not rocket science, I'm no professional and did knew it's a lower pitch with more water."๐Ÿ˜‚ 
When I was a kid I always use to make a sound blowing on top of a glass bottle the same way as a pan flute. When u drink a little the sound has a higher pitch. Maybe u should try.๐Ÿ˜‰

@ripsad1847

Those people definitely know physics.

@Asmoedi

that was beautiful

@drixx542

Heโ€™s right because more weight the pitch is lower because if there isnโ€™t as much weight itโ€™s lighter witch = a higher pitch

@BH-LGB

Anyone who things that doesnโ€™t understand how vibration works.
