It has been said that this book will deliver you to the devil of selling out! by try ing to be too commercial and mainstream, however I am currently reading this book and have to say that as a songwriter of only several months with my own band and making the recomended changes that have been "prescibed" in this book and can deffinatley here and feel a more catchy format.
Do these methods apply to rock music?
Yes!
Listen to every song that you love and make out the structure do you remeber the melody, does the chorus stand out!
These are general things that are not "pop" but that make the music of today in any Genre.
The writer Jason Blume is of a more "pop" background which you can seee by the refernces to the songs he has wrote in the book, but this allows you to see the types of songs that he has crafted and how they have worked in different settings.
this book is without a doubt the number one songwriting bokk out there, there are many books that claim to have all the information that you will require to make "Hit" songs, most I have bought from this site by doing exactly what you have done on the search believe when I say stpo wasting time and your money simply get this one first! I wish I had!
