Washington, July 2 (ANI): Contrary to all suggestions regarding Richard Wagner’s “difficult” reputation, a new study now suggests that the German composer used to set his text to music in a way that uses the acoustics of the soprano voice in a manner that helps both performers and listeners.

“Each vowel in European languages is associated with a set of resonance frequencies of the vocal tract,” says author Dr. John Smith, of the University of New South Wales.

“Both the intelligibility to listeners and the ease of production by singers could be improved if the pitch of the musical note written for a vowel corresponded with one of its resonance frequencies,” Smith says.

UNSW co-author, Professor Joe Wolfe, adds: “If this occurred we should expect to find that vowels normally sung with an open mouth would occur more often at the high notes of the soprano range.”

Writing about their work in the Journal of the Acoustic Society of America, the researchers have revealed that they tested this idea by examining the musical scores for eight operas.

For over 20,000 notes sung by solo sopranos in these operas, the authors recorded the vowel sound associated with each note.

In the Wagnerian operas, vowels that required an open mouth were used significantly more often for the very high notes. However, this was not the case for the other operas studied.

The researchers say that the preferential use of vowels in an appropriate range of pitch might have evolved because Wagner’s idea of opera was a continuous music drama in which singers often have to communicate lengthy, subtle aspects of plot via sung text alone.

Earlier operas often linked separate arias and choruses with the plot explained by recitative and actions on stage. There was thus less need for intelligibility at high pitch in these other operas.

The researchers further point out that Wagner wrote for much larger orchestras than available to Mozart or Rossini, and wrote vocal parts that severely test the stamina and capabilities of singers.

Thus, according to them, the employment of vowel-pitch matching could have helped satisfy the concomitant requirements of intelligibility, vocal power and easier singing of difficult parts.

“We know of no written evidence that Wagner tried to make singing parts easier for sopranos, but this research indicates that suitable matching of vowels with pitch increased systematically as Wagner’s experience as a composer increased,” says Dr. Smith.

Wagner was unusual as he wrote the librettos for all his operas, and thus had a distinct advantage in matching text with music.

Furthermore Wagner had considerable time to “polish” his operas. While Rossini wrote some 26 operas in seven years, Wagner wrote only fourteen in over 50 years. (ANI)
