  • Parsifal and Canada: a Documentary Study
    Parsifal and Canada: A Documentary Study The Canadian Opera Company is preparing to stage Parsifal in Toronto for the first time in 115 years; seven performances are planned for the Four Seasons Centre for the Performing Arts from September 25 to October 18, 2020. Restrictions on public gatherings imposed as a result of the Covid-19 pandemic have placed the production in jeopardy. Wagnerians have so far suffered the cancellation of the COC’s Flying Dutchman, Chicago Lyric Opera’s Ring cycle and the entire Bayreuth Festival for 2020. It will be a hard blow if the COC Parsifal follows in the footsteps of a projected performance of Parsifal in Montreal over 100 years ago. Quinlan Opera Company from England, which mounted a series of 20 operas in Montreal in the spring of 1914 (including a complete Ring cycle), announced plans to return in the fall of 1914 for another feast of opera, including Parsifal. But World War One intervened, the Parsifal production was cancelled, and the Quinlan company went out of business. Let us hope that history does not repeat itself.1 While we await news of whether the COC production will be mounted, it is an opportune time to reflect on Parsifal and its various resonances in Canadian music history. This article will consider three aspects of Parsifal and Canada: 1) a performance history, including both excerpts and complete presentations; 2) remarks on some Canadian singers who have sung Parsifal roles; and 3) Canadian scholarship on Parsifal. NB: The indication [DS] refers the reader to sources that are reproduced in the documentation portfolio that accompanies this article.

  • L'opera Famiglia PR .Qxp Layout 1
    November 10, 2020 FOR IMMEDIATE RELEASE Contact: James Cassidy (859) 431-6216 [email protected] L’Opera Famiglia (Two couples, great arias) 7:30 p.m. November 21, 2020 St. Peter in Chains Cathedral Basilica 8th and Plum Cincinnati, OH The Kentucky Symphony Orchestra continues its 29th season of in-person performances and live streaming with an evening of operatic and sacred arias. The KSO, over the last 20 seasons, has offered audiences complete concert operas — Tosca, Otello, La Boheme, Rigoletto, Samson & Delilah and Turandot. These productions featured a number of internationally recognized singers, many with local ties (CCM and the Cincinnati Opera). Four of these artists return as two couples for L’Opera Famiglia on November 21 at the Cathedral Basilica of St. Peter in Chains. Mezzo soprano Stacey Rishoi appeared in a KSO “Sopranos” evening and as Delilah (Samson & Delilah). Her husband Gustav Andreassen (bass) sang the role of Sparafucille (Rigoletto). Stacey and Gus when not on the road reside Bellevue, KY. Stuart Neill KSO at St. Peter in Chains Cathedral Feb. 23, 2020 (tenor) and Sandra Lopez (soprano) met as Rodolfo and Mimi in the KSO’s 2007 production of La Boheme. They were married a couple years later and live in Miami. “As with any team sport or artistic collaboration, cast chemistry is vital for success. We were fortunate for the stars to align to find these wonderful performers available this week,” commented KSO music director, James Cassidy. Those who don’t think that opera is their cup of tea, might be surprised to find many of the selections on the program very familiar to a universal audience (see below).

Examination Committee Member Dean Gronemeier, DMA, JD. Examination Committee Member Joe Bynum, MFA. Graduate College Faculty Representative ii ABSTRACT This doctoral dissertation provides information on how to develop the young dramatic soprano, specifically through more concentrated focus on the breath. Proper breathing is considered the single most important skill a singer will learn, but its methodology continues to mystify multitudes of singers and voice teachers. Voice professionals often write treatises with a chapter or two devoted to breathing, whose explanations are extremely varied, complex or vague. Young dramatic sopranos, whose voices are unwieldy and take longer to develop are at a particular disadvantage for absorbing a solid vocal technique. First, a description, classification and brief history of the young dramatic soprano is discussed along with a retracing of breath methodologies relevant to the young dramatic soprano’s development.

  • Rimrock Opera Presents
    Rimrock Opera presents Special Student Performance April 28, Thursday 9 – Noon Public Performances April 30 & May 1, 2011 Alberta Bair Theater, Billings, Montana Rimrock Opera History Until the founding of the Rimrock Opera in 1999, opera was a scarce commodity in Billings. Occasional opera performances by touring groups attracted large audiences even though the accompaniment was usually provided by piano rather than orchestra. One notable exception was the 1964 Territorial Celebration tour of Puccini‟s Girl of the Golden West, produced by the University of Montana and presented in a dozen sites throughout the state including Billings‟ Fox Theater. Included in the tour cast were Lee Mathews (who subsequently was the stage director for the 1989 premiere of Pamelia at the Alberta Bair Theater) and Edward Harris (who helped in starting the Rimrock Opera). In the 1970s, the presence of guest artist Julian Patrick at Rocky Mountain College made it possible for RMC‟s Don Pihlaja to produce The Old Maid and the Thief and Down in the Valley. In a burst of venturesome programming, Billings Symphony Orchestra conductor George Perkins directed a Billings production of The Magic Flute in 1973. (Included in the local cast in his first operatic experience was Douglas Nagel as Papageno.) Perkins later directed a lavish local production of The Mikado which featured sets designed by famed artist Hall Diteman. The opera Pamelia premiered at the Alberta Bair Theater in 1989. Pamelia combined local and professional talents and was made possible largely through the fund-raising work of Billings volunteer Ellen Alweis. The Western Opera Company presented its touring production of Die Fledermaus in October, 1993.

The difficulties arise from the lack of markings in some cases, ambiguous or impractical markings in others (with some evidence that at times Puccini himself was not reliable in this matter), doubts about the authorship of some markings, and wide variations in tempo among recorded perfor- mances.

  • Puccini — TOSCA
    Puccini — TOSCA TOSCA Leaves Audience in a Good Mood, Wanting More! "The traveling production of TOSCA by Teatro Lirico D'Europa left the CAPACITY audience in a good mood, wishing for more. Soprano, Victoria Litherland, was excellent in the title role. She has sung TOSCA before with the Austin Lyric Opera and last week was in Seattle, starring in MANON LESCAUT. She was paired well with tenor, Cesar Hernandez as Mario. Baritone, Vailry Ivanov was appropriately villainous as Scarpia, emphasizing the character's sadistic side rather than his mock piety. The secondary characters were well sung. The sets and costumes were first rate. Everyone deserved the long standing ovation at the final curtain." PORTLAND PRESS HERALD — Christopher Hyde — February 2004 Teatro Lirico's TOSCA Comes Up Big! “Everything about Friday's TOSCA, the outstanding final program in the Symphony Society's International Series, was big. From the moment the curtain rose, it was clear that the nearly 50 members of Teatro Lirico's orchestra were too many for Peabody Auditorium's pit. The result was a voluminous sound, just right for the outsized passions in the opera and for the singers who expressed them. Under the direction of Giorgio Lalov, the focus is always firmly on the romantic tragedy TOSCA represents. Teatro Liricoʼs cast, elegantly costumed and supported by an orchestra able to express the operas immense emotions, was tremendous in their ability to make every nuance felt. In the title role, the young American soprano shone. Pearce's voice, rich and warm, shifted with emotions that spanned the gamut, and her acting made marvelously theatrical gestures entirely believable.

  • An Analysis and Discussion of Zwischenfach Voices by Jennifer
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by ASU Digital Repository An Analysis and Discussion of Zwischenfach Voices by Jennifer Allen A Research Paper Presented in Partial Fulfillment of the Requirements of the Degree Doctor of Musical Arts Approved April 2012 by the Graduate Supervisory Committee: Carole FitzPatrick, Co-Chair Kay Norton, Co-Chair Dale Dreyfoos Russell Ryan Robert Barefield ARIZONA STATE UNIVERSITY May 2012 ABSTRACT Zwischen in the German language means ‘between,’ and over the past century, as operatic voices have evolved in both range and size, the voice classification of Zwischenfach has become much more relevant – particularly to the female voice. Identifying whether nineteenth century composers recognized the growing opportunities for vocal drama, size, and range in singers and therefore wrote roles for ‘between’ singers; or conversely whether, singers began to challenge and develop their voices to sing the new influx of romantic, verismo and grand repertoire is difficult to determine. Whichever the case, teachers and students should not be surprised about the existence of this nebulous Fach. A clear and concise definition of the word Fach for the purpose of this paper is as follows: a specific voice classification. Zwischenfach is an important topic because young singers are often confused and over-eager to self-label due to the discipline’s excessive labeling of Fachs. Rushing to categorize a young voice ultimately leads to misperceptions. To address some of the confusion, this paper briefly explores surveys of the pedagogy and history of the Fach system. To gain insights into the relevance of Zwischenfach in today’s marketplace, I developed with my advisors, colleagues and students a set of subjects willing to fill out questionnaires.

Besides being great tenors, each of these singers share the fact that they transitioned from baritone to tenor. Perhaps nothing is more destructive to the confidence of a singer than to have his vocal identity or voice type challenged.
