The Baritone is similar to the Euphonium in terms of shape, pitch and range, except that the larger bore of the Euphonium gives its lower notes a broader and mellower timbre.
Methods Video-stroboscopy was used to reveal the laryngeal cavity and dynamic changes of the vocal fold, and sound spectrograph was used to examine audio frequency, pitch and width.
Naturally people can't appreciate what they can't see, just as we all have different ranges for singing, hearing pitch, and seeing colors, we have different ranges for seeing and understanding things.
So I've always struggled with high notes, but I have been practicing and working with my vocal coach to be able to just like expand my range and learn some new stuff, okay.
