This is for my other technique post e.g. asking if this example is mix voice. Please don't critique unless you are looking to answer the question. I tried to keep the high notes from 'releasing', because I think that a rounded mix represents how it would work with legato, where as a released sounding mix may not work in legato phrasing. Sound-clip is amplified to 0db by default.

So as the title says, stuck at F4 and can't go above it. Despite good adduction,twang,and appoggio. Once I hit G4 the balance starts faltering. I can sing above F4 with consistency but there's always some compromise, usually either a thinning with loss in body, or keeping the body but loss in upper ring.
