Customer Reviews

A Gold Mine for Musicians and Music Teachers

I have taught music privately and in the classroom for over 30 years,

and it would have been so much easier – and better –

with a resource like Garage Band Theory.

How a book can be simultaneously so encyclopedic, so instructive

and so hugely entertaining is beyond me,

but I hope it ends up in the hands of every music teacher

and professional musician who can obtain it.

The index never fails to direct me to a topic I want,

and the many quotations pertaining to music,

art and life reaffirm the author’s passion

for this essential component

of what it means to be human and creative.

No matter what instrument you play, or what style,

or for what purpose,

this resource will prove indispensable.




“I wasn’t sure about the price,

but it turned out to be worth it.

Garage Band Theory is a kind of musical bible

that you’ll use a lot.”

“Duke breaks it down so that anyone

can have a great grasp of music theory

and how to play by ear.”

“Who knew music theory could be this much fun?”

“This book is comprehensive,

but is set in the language of every day people.”

“It’s easy to work with

and super easy to track your progress

with fill-in-the-blank quizzes.”

“The narrative is breezy and light

and pretty funny in parts,

which makes you want to keep going.”

“It can be used as a reference book,

instructional aide and/or lesson planner.




Amazing Tool for teachers and students.

As a music teacher I am often challenged

by trying to explain

simple but important theory concepts to students.

Without overwhelming them,

I want to share the basic ideas of the language of music.

In this book, Duke has a real way with words.

He’s given me new and friendly ways

to share this vital information.

Garage Band Theory is an amazing tool for both teachers and students

from beginning to advanced




“For $40 of overall cost,

I’m very impressed with what I got out of this book.”

“It’s got everything you need to ‘learn to speak music’

and develop your improvisational skills.”

“You get a lot of bang for your buck!

“Read the reviews by professional musicians

who know what they’re talking about.”

There are a few minor typos/errors,

but it’s so well explained that even I can understand

when there are errors.”

“It’s a complete course in music theory

written so regular folks can understand it.”

“The added bonus

is you start to become able to talk to other musicians

knowledgeably.

“What a great value.”




Finally… a music theory book that’s enjoyable to read!

Who knew music theory could be this much fun?

What was a distinctly dull and dry subject in college comes alive in this book

with clear explanations, humor, and real world examples.

This book will be useful

for the beginning musician and veteran alike.

It can be used as a reference book,

instructional aide and/or lesson planner.

If music theory is the written language of music,

this book is the Rosetta Stone.




“If you want to communicate with other musicians

and sound like you know what you’re talking about,

this is for you.”

“I have several books on theory

and this by far is the most approachable.”

“Don’t forget to reach out

and get all of the digital resources he provides.”

“Wonderfully readable!”

“I loved the examples on various instruments.”

“It’s also by turns both funny and inspiring.”

“Garage Band Theory looks at the subject a different way,

where music “theory” is just a common language

that allows people making music talk to one another.”

“I liked that each section presents a concept, uses some real-life examples,

then gives you an exercise or two to make sure you understand.”




Excellent.

I have a degree in Music Education

and used to grade Freshman class theory exams

at Montana State University.

I have learned from this book.

Even though the author is a guitar and mandolin player,

“Garage Band Theory” applies equally to all musicians,

at all levels of proficiency and understanding.

Beginning students and experienced players

will all glean valuable information.

Well done, clear easy to understand information

presented in a logical order.




“I am amazed how comprehensive this volume is!”

“Duke’s book has, by far, the clearest explanations

of music theory concepts I’ve come across.”

“Awesome book,

explains everything you need to know about music theory

for guitar in a clear, enjoyable way.”

I also found the suggestions on practicing awesome.

Don’t expect you are going to get anywhere

without putting the time in.

Great advice.

Great reference for every musician, just starting out

to those who have been doing it for years.”

“Duke has a way of teaching that is so comfortable.

Anyone can learn from this book.

He makes it so easy!”

“Awesome book with great info for players

of guitar, violin, mandolin, bass and piano.

Highly recommended”

“A breakthrough method in teaching the intricacies of music

in a very easy to understand way.”

“I really enjoy the breezy attitude,

but as a reference

this book is no joke.”




A Massive Book Full of Information

I have a LOT of music books.

Some of them are good.

Some, well, not so good.

I’m happy to report this book is AWESOME.

It’s huge, full of great information for several instruments, and is a great reference.

Definitely a favorite part of my music book library!




“Duke is a personable writer with an ironic sense of humor.”

“Great information- presented nicely.”

“Practical and useful.”

“Awesome book, and fun to read”

“His style of writing is enough to keep me entertained.”

“I bought it to give as a Christmas gift to my ten year-old nephew, but couldn’t wait for the holidays—he’s already on the Introduction to Moveable Forms scales practice.”

“A wonderful investment, full of insight and information”

“Excellent resource.”

“I have bought at least a dozen ‘how to’ books on the rudiments of music. This one has put them all in the shade.”




Funny Writing & Comprehensive Activities

This book is great!

Although its heft is a little daunting at first,

every page is filled with valuable lessons

written with an entertaining and comedic voice.

The exercises/activities wrap up each chapter nicely

and make it easy to refer back to my notes on each topic.

Wonderful book for learning how to play by ear,

understand the basis of reading music,

and composing your own songs.




“It’s super easy to track your progress

with fill-in-the-blank quizzes.”

“I wish I’d had this when I started playing music

many decades ago, but I’m happy to have it now.”

“It answers the “Why?” of music theory

for all those people who dislike stuffy academic books.”

“It’s actually a fun read.”

“It is BIG, and chock-full of great information,

really nuts-and-bolts stuff.”

“Things are broken down clearly, and step by step,

so that even a child could be taught to play

and jam with others quickly.”
