DR Matthew - The Key 3 Book for the current revival of
A Chorus Line is mainly the new string parts that Mr. Tunick incorporated for the revival. -The original had no strings - live or otherwise. There's a little bit of harpsichord, and I also get the funky organ and synth stuff in "Music and the Mirror". So, basically, it's the new string book with bits and pieces of the old conductor's keyboard part. In other words, it's very easy.

Lots of whole notes. Lots of "Tacet". Lots of rests. Consequently, the book has been called the "Coma Book" since it could be very easy to fall asleep and/or to lose count.

Key 2 covers the guitar, harp and some Rhodes. Key 1 is piano (of course), celeste and some Rhodes - it's almost like the original book. Strangely enough, the "Tap Dance" was re-done, and now the piano plays even more of it than before. -And that stride piano ain't easy.
