I don't know if to get rid of some legal process or get rid of the google search robots, or picking up inattentive people, the word above Julliard was purposely written wrong. But as I never let out anything at all, b u t Juilliard is correct, Just missed an ' i '.
Just to point again, that this book has nothing to do with 'Juilliard School', but, his author only uses the old 'Juilliard School music system', "of?". By the way, abandoned, Juilliard tried to innovate, but hardly failed. Recently in 2001 they opened the 'Juilliard Jazz Studies', with the direction of 'Wynton Marsalis'.

It is good to know that until today there is not one international standard encryption of the chords symbols. 'USA' uses one for example; Major Seven to maj7, some use 7M or one delta 'Δ', some other American schools tried to apply some other rules, like to design another cabalistic russian alphabet to have a personal signature for their schools, but did wrong to be alone, while other countries use other symbols to specify minor, major seventh etc.
Some use symbols after numbers: 'X' , 'Δ' , ' + ' or ' - ' , 'sus', 'au' , 'alt', 'add2, 6 or 13' , / , |...(bass) 'phryg', '(lydian)', '(super-locrian)', '(aeolian)' 'm', 'M', 'dim', '(no 3rd)', 'b' or '#', ° , 'Ø' , 'ø', 'x', ' , but no one is wrong. For example, can be confused when we read scores from other countries, it depends on where you are, for someone who reads a C7+, some don't know if is it a major 7th or an augmented 5th, then, consult your area.
We have only 'Roman Chord numbers' in 'Traditional Harmony' that is a true convention, an empirical process that was improved over centuries by musicians far better than those we have today and therefore reached such perfection that it will never be modified, anyone who attempted such a feat fell into anomic. Until today no convention for 'pop chord symbols' was created.

The strangest thing I've ever seen in sheet music, are those produced for accordions, when you notice, a number '1' over a note, it means that is a major chord, if there is a number '2' on a single note, it means this is a minor chord, but if above a note it has the number '3', it means that this chord is a 'V7' chord, major third with a minor seventh, the dominant chord, if the number is '4', it is a diminished chord.
Curiosities about the accordion, numbers 1,2,3 and 4 that appear above the highest notes of the bass clef or below the chord symbol. Eg. in the accordion sheet music:
Eb = Eb, Gmi=Gm, Fs = F7, and last C = C° or Cdim
_1________2________3________________4______ (Number under the Chord letters)
                                
This is because the accordion has only four chord buttons, each button one chord, the first one after the bass, is the major button = 1, then the minor = 2, the dominant = 3 and finally the diminished = 4.
That is 1, 2,3 and 4, major, minor, dominant seventh and diminished.
But, if the letter 's' comes after the chord symbol, it means that it is a' V7' chord, as they usually say, "dominant seventh chord".


This book, between the others is the most I lthink useful, is a short compendium of piano arrangement, with lots of useful info and good tips.
Without day by day training: 'chord inversions' or scales and other tricks, forget the hard work of studying music, prefer your TV Set that brings everything already thought, so you don't have to spend neurons.
