Theory Essentials An Integrated Approach to Harmony 2nd Ed.

Great share Oly, thank you very much.

Many AWFUL ERROS inside this book, many are simply Edition Erros and most of them amateurs musicians trying to explain the existence of Music Theory.

1º of all there no theory for music, but just lots of information or material to use.
On page 3: The "Treble Clef" changed the name to Bass Clef and the "Bass Clef" is now the "Clave da Violino"
Now imagine someone learning music from beginning throughout this book.
The first "C Clef" disappeared here, but is still used today to read old papers for soprano voice. Must simple say that was used for 2 centuries.

On page 38: [Eighths, or octaves, are special intervals. When you start with any letter of the musical alphabet as the first note of an interval and count up eight notes... ]
The Octave is not a special interval, really! It´s just another interval with it´s own mathematical characteristics. What is musical alphabet? Never existed! The author make some confusion with the the small 8 letters of occidental Greek-Latin alphabet used as association with tones.
There is 8 Germanic notation, A, B, C etc. The rest of 16 known letters were not used as attribution within tones.

<spoiler>Read the rest</spoiler>
Another tip, be careful cause today we think in globalization, to earn money selling books through Amazon, there are Russian, Greek, Chinese, Japanese Alphabets, and they are quiet different.
The old 8 notes scales is just ONE REFERENCE to do music, Stravinsky composed his own scales, Atonal twelve-tone music in Germany used the letters to do music and after 8 notes the scale do not repeat.
But the worst ERROR is: counting up eight note of what scale, we bet on diatonic scale, not chromatic, must say: diatonic scale, not octatonic etc;

On page 52: Prefer "Paul Hindemith" book to build your "Rhythm Menu", never count (1 & 2 &...) Do it using a pencil on the table, voice and feet, warm up your brain to realize musical figures and feel the rhythm, is simple as reading any word. This is just a tip, because many students create addictions and never get clever on reading, Guitarists have this problem. But remember to never count or think on the counting process.

On page 81: Such a confusion in his mind, with the word "bass". The author must try a class of etymology, to know more about the word "bass", that is something in the ground, lower part, but as a reference only. He says that was used to name the "bass clef", as we know, but the expression "figured bass" is exactly the REFERENCE of any note in relation to the bass, to the ground tone, to the "basis" tone. But not that the word "can" also applied to another structure, the word is applied because of it´s functional
sense, logical sense of use, bass is used since the Baroque era up today. "Hugo Riemann" tried to change it in Germany, but he him self perceived he was wrong, and abandoned the new harmony project, of course fail, he started using the same roman numerals with Arabic numbers, bad.

On Page 92: "lowercase roman numerals" never existed, I swear by all Romans, it is an application created by the respected authors "Dorothy Payne and S. Kostka" to make harmony understanding easier, is it true that Americans did not contributed to musical therms used today, some are simply copy of Debussy, but Kostka contributed to the small mirrored roman characters, so you can imagine diminutive numbers, that never existed any where. Today many schools of Europe, Japan etc use these
small letters, but one of the most important from North America, so you can fast imagine that: "I is i or VI is vi" Author must take care with text and his own guesses about things, the Idiot's theory was better written.

Take care with the therm progression, wrong used by Americans, simple chords are not chord progressions, they bad influenced many countries, or, if they want to use that on their own understand, must quote therms to not confound within 3 centuries of usage in music.

page 222: [Appoggiatura mean "to lean"]. No, better rely. the author didn't understand that, the more simple structure of music. He "theorize" about fourth interval to explain a simple appoggiature, do not exist, listen to the king of the kings of "appoggiaturas", Mozart.
This word simply means: Drop a tone on a wrong position of chord and resolve up or down to the diatonic or chromatically to the closest tone, including the seventh. That´s Simple.

And there are many more stupidit I don't have time to write:
page 95: Cadence in music is a stopping place...the end of an entire composition... Uhh! tell me about the cadence V-vi, what is it, music does not end, take care with what you have written, confound people so much the idea of End.
Cadence come from "Latin, means cadere", to fall, to die, you can finish anything if you want, do not depends of cadence. After the "V" we fell the sensation of falling cadence, but, after o "V chord", we can use the "I6 or the tonic with the 3ª in the bass", so, the music not ended, "IV to I" is also a cadence and end the music without the V-I chords. Must review concepts.

Now I understand, why so many people don't know to talk about music, having small portion ideas, when listening to simple chords with appogiaturas they can be magnetized. If you think this way, you can't say your self you're musician. You are an amateur, true musician have decoded all the codes, so they starting listening and playing another way, is like an adult remember when was a child.

By the way, in my perception, I see many musicians who failed to be musicians, and they caught the commercial vein to sells their books. Dig the life of these authors and will be disappointed, they never appeared in anywhere, TV, show, youtube, some of them just tell that played with someone famous etc. But you'll be disappointed. There are more books to sell than musicians, and the musician in the market never wrote a book, except those invited by the publisher to earn more money in the end of career, play Elvis, play Bob Dilan etc </spoiler>

Don't recommend this book.
