Singing Crystal Wineglass -- Does the wine mass determine the pitch?

[Twodogs]

TL;DR Summary

Increacing fluid in glass lowers the pitch of the tone.
What part does the fluid play in sound dynamics?

"When you stroke the top edge of a crystal wine glass half full of wine, a musical tone is produced. Is the wine mass part of the determinate of pitch? Is the water vibrating at that pitch?"

I asked asked ChatGPT this question. It did not call me an idiot for posting a questionably formed question, but I am looking for a more fulsome answer.

One online experiment video demonstrated that the more fluid (let's say Wine).. the more wine in the glass the lower the tone. The video attributed this to the mass of the wine -- the more wine-mass to accelerate, the less acceleration (m/s), thus lower the tone.

I am thinking that the tone produced is a dynamical joint venture at the interface between vibrating Chrystal and Wine body. The driver of the dynamic is the vibration produced by a moist finger tracing the edge of the glass. The stroking cycle is slow and inexact, but the dynamical response of the joint system, its resonant frequency is more exacting, say in the range of middle C, say 262 Hz or 262 cycles/second.

So question, can you give some insight to the dynamics here? Is there ambient energy, a flux through points within the Wine body?
Thank you.

I was going to post the ChatGPT reply here, but I think it would just distract.

An empty glass also produces sound. Watch this video. It explains everything and is made by real humans.

Thanks, makes sense and glad I did not do that.
