Note : I perform nearly all major oratorio repertoire from memory. My aim is always to remove the barrier of the score so the audience and conductor experience direct communication — facial expression, textual clarity, and expressive immediacy. If I reference anything, it is only a printed page with key verbal cues or phrasing marks. A conductor once told his chorus during rehearsal for the Verdi Requiem:   “He understands every word he sings.”   A background in Latin, along with sentence-diagramming of crucial text passages across opera and oratorio, ensures complete alignment of intention, meaning, and vocal delivery.

Daily Conditioning (as discussed)

These 25 roles are supported by a rapid-recall conditioning system done daily:  
  • Marchesi Chromatic Scale — performed while a weighted hula hoop rotates around the waist, and while turning in a circle
  • Short Runs — Vaccaj
  • The Dotted Melody — Marchesi
  • Custom “Pencil Fall” Register Shift Exercise
  This maintains top-to-bottom flexibility, agility for Rossini, coloratura facility, and low-range power for Verdi and Wagner.
