Very Pretty - Not So Helpful . Sigh... Like most of Andrew Lloyd Webber's sheet music, selections from Phantom of the Opera gives you a watered-down transcription featuring many cuts. Even worse, the accompaniment is hardly the original accompaniment at all, rather it simply follows the vocal line. This might be acceptable for fans who simply want to play through the music on their parlor piano without a vocalist, but for a real musical theater fan, it's very disappointing. So far, I've only found one place which gives an accurate transciption of the accompaniment (an excerpt from the full piano-vocal score). The Singer's Musical Theatre Anthology: Soprano, Vol. 3, compiled by Richard Walters features "Think of Me" and "Wishing You Were Somehow Here Again" in their original form. For performers and accompanists alike, there's something to get excited about. So far, we're still waiting on more from the Phantom of the Opera, but they're creating a 4th edition of the Anthologies soon, so watch out
Output:
NEG
