The present edition dates from 1986 and the books are getting worn. A new edition is planned, though that is some way off, and an interim book is about to be published.
There are three changes I would like to see. The first would keep the Mass and Kyriale in the middle of the book, to make the books more durable, but to distinguish them in some way, possibly by printing them on coloured paper or through the use of tabs or some other kind of book mark. Alternatively, it might be advantageous to put the Mass and Kyriale in a separate small book. It is worth thinking about.
The second change concerns the Latin texts, the use of which is slowly increasing. For those who do not know how to read music, the Gregorian four line/square note notation is easier to learn, as the neums show the shape of the musical phrases more graphically. It is also the case that information is lost when Gregorian chant is written in modern notation, with a tendency for it to sound flat and boring. It would be advantageous if the opportunity were taken to use the Solemnes settings as printed in the Graduale Romanum or Liber Cantualis. Using scanning techniques, this should add nothing to the cost apart from copyright payments.
The third change is that the text and rubrics of the Extraordinary Form of the Mass now need to be included.
