No more arpeggios in the bathroom. Goodbye, church basements. Hello, soundproofing.

Opera America, a service organization for opera companies, is opening a new National Opera Center in Manhattan filled with rooms for auditions, rehearsals and lessons. Opera company officials say it will be a major boon for singers and for the regional ensembles that troop through New York every year to audition them, often in less than ideal circumstances.

The center will also offer a rich library of scores (many donated by the conductor Julius Rudel), books (likewise, by the set designer John Conklin) and video and audio recordings. It will present seminars, public conversations and performances, including concerts of 47 songs commissioned in honor of the center’s opening. A recording studio is available for young singers to make audition CDs and DVDs.

The center is the latest addition in a mini-surge of new spaces in New York available for performers. They include the nearby DiMenna Center, which began operations last year, and the Original Music Workshop in the Williamsburg neighborhood of Brooklyn, which is scheduled to open late next year.

The opera center is expected to play a crucial role in the operatic biosphere, which depends on a steady supply of young singers, many of whom regularly display their wares for regional casting officials in New York.
