Reddit reviews Song Means: Analysing and Interpreting Recorded Popular Song (Ashgate Popular and Folk Music Series)

Depends on what sort of rep you're in to (into?). I read a lot of popular music scholarship. These are books that I have either read or am going to read, in no particular order:

Brad Osborn - Everything in its Right Place: Analyzing Radiohead

Robert Walser - Running with the Devil:Power, Gender, and Madness in Heavy Metal Music

Walter Everett - The Foundations of Rock

Walter Everett - The Beatles as Musicians: The Quarry Men through Rubber Soul, Revolver through the Anthology

† Understanding Rock: Essays in Musical Analysis, ed. John Covach and Graeme Boone

Richard Middleton - Studying Popular Music

Allan Moore - Song Means:Analysing and Interpreting Recorded Popular Song

†Analyzing Popular Music, ed. Allan Moore

† = A bunch of essays crammed into a book. These are nice because you can read a 20-50 page study on a topic and move on.

I'll recommend these as more general reading, geared toward classical music but useful in other styles as well:

William Caplin - Classical Form: A Theory of Formal Functions for the Instrumental Music of Haydn, Mozart, and Beethoven (Every researcher in the field knows or should know this one. I would also recommend Hepokoski and Darcy - Elements of Sonata Theory, which is the other big form book, but it is a veritable tome and hardly light reading. Not that much of what I've recommended is very light.)

Janet Schmalfeldt - In the Process of Becoming:Analytic and Philosophical Perspectives on Form in Early Nineteenth-Century Music (I haven't read this yet, but it's in the same universe of form studies as the above.)

Kofi Agawu - Music as Discourse: Semiotic Adventures in Romantic Music (Agawu has written a lot on various topics and should be on your radar.)

Alfred Mann - The Study of Fugue (Broken up into two parts: part 1 is a history of fugue, part 2 is about fugal technique.)

I'll point you toward this one since it is totally awesome and helped me to understand medieval liturgical music theory and culture (though you might find yourself lost if you are not already familiar with some of the concepts):

Anna Maria Busse Berger - Medieval Music and the Art of Memory

You might also consider ordering a hard copy of some journal issues, as these can be quite compact and give you a lot of breadth.

Journal of Music Theory (JMT)

Music Theory Spectrum (MTS)

I think every theory book I've ever read has opened up my mind in some way - while always being unsatisfactory in other ways (incomplete, too dense, too little on some forms of music, etc). My experience and interest is largely in popular music of all kinds, less in classical, so that has biased my reading somewhat; but I can recommend all the following (not 100%, but worth reading):

Eric Taylor: The AB Guide to Music Theory, pts I and II - good review of the basics, aimed at pupils studying for grades. Not deep in any way but good if you're just starting out. Solidly classical, which could be a downside for some. The concepts up to grade 5 are shrunk to useful pocket size in [this] (https://www.amazon.co.uk/First-Steps-Music-Theory-Grades/dp/1860960901/ref=sr_1_1?s=books&ie=UTF8&qid=1466150641&sr=1-1&keywords=theory+of+music+grades+1-5) - 100% recommended for any absolute beginner.

George Heussenstamm : [Harmony and Theory, pts 1 & 2 (Hal Leonard)] (https://www.amazon.co.uk/Hal-Leonard-Harmony-Theory-Diatonic/dp/1423498879/ref=sr_1_2?s=books&ie=UTF8&qid=1466150878&sr=1-2&keywords=Hal+Leonard+Harmony+%26+Theory) Usefully split into Diatonic and Chromatic. I've read a few texts on standard classical theory, and this is the most approachable, IMO.

William Russo: [Jazz Composition and Orchestration] (https://www.amazon.co.uk/Jazz-Composition-Orchestration-William-Russo/dp/0226732150/ref=sr_1_1?s=books&ie=UTF8&qid=1466151290&sr=1-1&keywords=russo+jazz+composition) Taught me more than I thought I wanted to know about counterpoint. Most of which I've now forgotten (not much call for it in the bands I played in...). But if you're not into big band jazz (at all), maybe not worth it.

William Russo: [Composing for the Jazz Orchestra] (https://www.amazon.co.uk/Composing-Jazz-Orchestra-William-Russo-ebook/dp/B01EZ8OKQW/ref=sr_1_1?s=books&ie=UTF8&qid=1466149432&sr=1-1&keywords=william+russo) Neat little guide book on jazz arranging (NOT composition).

Mark Levine: [The Jazz Theory Book] (https://www.amazon.co.uk/Jazz-Theory-Book-Mark-Levine/dp/1883217040/ref=sr_1_1?s=books&ie=UTF8&qid=1466151006&sr=1-1&keywords=levine+jazz+theory) 50% recommended. Well written and presented, eye-opening in many ways, but beware - chord-scale theory! (controversial stuff, in ways he doesn't admit.)

Robert Rawlins and Nor Eddine Bahha: [Jazzology] (https://www.amazon.co.uk/Jazzology-Encyclopedia-Jazz-Theory-Musicians/dp/0634086782/ref=pd_sim_14_5?ie=UTF8&dpID=41YkvVcCfEL&dpSrc=sims&preST=_AC_UL160_SR120%2C160_&refRID=ZR730GKYPSZYA2THNXGT) The somewhat dry antidote to the above. 50% recommended. Should have been good, but somehow hard to read, easy to put down. Unlike Levine, no quotes from jazz standards or recordings - all music examples are written by the authors.

Dominic Pedler: [The Songwriting Secrets of the Beatles] (https://www.amazon.co.uk/Songwriting-Secrets-%2522Beatles%2522-Dominic-Pedler/dp/0711981671/ref=sr_1_1?s=books&ie=UTF8&qid=1466151087&sr=1-1&keywords=pedler+beatles) Outlines the vast number of theoretical concepts that the fab four would be astonished to learn they employed. Includes a useful appendix on basic concepts of tonal harmony. If you like pop and rock (and theory) but don't like the Beatles, still worth reading.

But then if you like the Beatles AND theory... [Alan Pollack's site] (http://www.icce.rug.nl/~soundscapes/DATABASES/AWP/awp-alphabet.shtml) is essential reading. (Pedler is deep, but doesn't examine EVERY song. Pollack is briefer, but does.

Allan F Moore: [Song Means: Analysing and Interpreting Popular Song] (https://www.amazon.co.uk/Song-Means-Analysing-Interpreting-Recorded/dp/1409438023/ref=sr_1_1?s=books&ie=UTF8&qid=1466151140&sr=1-1&keywords=allan+moore+song+means) Does what it says in the title - and goes deep! (way beyond the plain old superficial harmony concepts peddled - sorry - by Pedler :-))

Walter Everett: [Rock's Tonal Systems] (http://www.mtosmt.org/issues/mto.04.10.4/mto.04.10.4.w_everett.html) More stuff to raise the eyebrows of any rock musician. "Wow - we really do all that?"

Paul F Berliner: [Thinking in Jazz] (https://www.amazon.co.uk/Thinking-Jazz-Infinite-Improvisation-Ethnomusicology/dp/0226043819/ref=sr_1_1?s=books&ie=UTF8&qid=1466151218&sr=1-1&keywords=thinking+in+jazz) Not a music theory book in the usual sense, but discusses how jazz musicians think about improvisation.
