Giovanni Battista Lamperti was a highly-regarded Italian singing teacher who was considered to one of the best of his era. Many of Giovanni's students became international opera stars. These vocalises are designed to prepare the soprano voice for performance. "I recommend the daily use of these Exercises, particularly to Soprano and Mezzo-soprano singing a melodramatic repertory; because exercises of this kind promote length of respiration, and delay the deterioration and undue vibration (tremolo) of the voice. Beginners should confine themselves to a regularly limited range, so as not to weaken the medium of the voice and should extend their compass according to individual progress and development." - G.B. Lamperti
