"The author has interpreted these words with rapid sextoles (groups of six notes) and triplets in difficult intervalic skips, and finishing with an intricate florid cadenza in seconds and thirds. Many passages of the same form may be found in Handel's 'Messiah.' The young lady not only glided over these difficulties with ease and grace, but also brought out the _espressivo_ so necessary for the effective rendition of this division. The remaining portions of this fine composition are much varied with rapid executions; and the compass of voice required for effect is extensive, ranging from C above the staff to C below. Every point was delivered by the young vocalist with purity and force. "I believe this young lady's compass of voice is from E flat above the lines to A below; having at her command the soprano register, the mezzo-soprano, and a portion of the alto. "Both of the sisters sing in the Italian with fluency and with correct pronunciation. "'Par Excellence,' sung by Miss Emma, was a complete triumph with the audience, and received a triple call. This was a great compliment after Lingard, the original. But it was the lady's pleasing manner that took the comic-loving patrons by storm: hence the third encore." After the performance described by Professor Tullidge, the Misses Hyers were tendered by the leading citizens of Salt-Lake City a complimentary benefit.
