And this is the one to get.
I carry this book wherever I go, and thanks to its simple layout of staves and writing space, I can easily refer to my ideas. The paper is good quality, and the quotes on each page are inspirational. I love its antique look, but it never tries to be over-the-top with the art design, or over-commanding with its sectioning.
This book is good for orchestral writing, but i feel it's aimed at more pop song writing. Each page is largely manuscript, and has 10 guitar chord diagrams, and below, two groups of staves containing the following: a treble clef stave (for the melodies), then some writing space below (presumably for the lyrics, but I use this space for my notes), a treble/bass stave, and lastly a tablature stave.
All in all, a fancy looking notebook that does its job.
