Longe mala by Antonio Vivaldi, sung by Australian countertenor David Hansen. While there are some minor balance issues in this recording (I blame the microphone placement, not the performers!), I love the way that Mr. Hansen OWNS the opening cadenza. Listen carefully to the way that he keeps his voice engaged while backing off on air pressure as the line ascends. This optimal approach allows the vibrating portion of his vocal folds to shorten between E5 and F#5, allowing for a beautiful and easy sounding A5! This is a great illustration of the description of how countertenors can navigate their upper range from my previous post on countertenor technique.
