| For the others, 
                    it is enough to follow the same rule. No school 
                      will be complete without inverted time included in its teachings. 
                       Until current 
                      times, musicians have only improvised in 
                      terms of melody, Cado has created the harmonic improvisation 
                      and feels rather optimistic that in the future  people 
                      will study and make improvisations both harmonically and 
                      melodically. No musician 
                      that makes improvisations and harmony will be complete without 
                      harmonic improvisation.  In short, Cado will launch 
                      a book entitled "XX Century." Therein 
                      one will find greater explanations of inverted 
                      time,  harmonic improvisations, study techniques and 
                      atonal harmony. Music is 20% training, 20% 
                      culture, and 60% the enlightenment of the 
                      artist's creative capability.One may acquire 
                      training and culture at music schools and universities. For all to have an idea of 
                      how important this artist is 
                      to music, it is necessary to discoss 
                      the history of music. Initially,music was 
                      only melodic.First came vocal music 
                      and 4-shaped time ( natural ).Then 
                      musicians constructed the first scale and 
                      people discovered tonal relationships 
                      and other scales. 
 When music was solely melodical, musicians 
                      composed counterpoints with two, three or more melodies 
                      played at the same time, reaching polyphonies of up to 60 
                      voices.This was during the 
                      baroque period.Bach discovered a relationship 
                      between notes when played at the same time. Music, 
                      which was only horizontal, became vertical(Debussy 
                      made harmony before this, but using another technique).
 
 Since then, therehave been many 
                      harmonic discoveries such as the seven chords 
                      of  tonality, chords borrowed from other tonalities 
                      and modulations with artists such as: Bach, Mozart and Ravel.
 
 Mozart took musical discoveries 
                      to extremes, therefore everything was known at the level 
                      of functional harmony. The first measures were in 4, 2, 
                      3, 5, and 7, quaternaries, binaries, ternaries, and later 
                      on alternated, simple and compound measures.
 
 It was believed that great artists of the 
                      past had already discovered everything at the level of musical 
                      time (except for the inverted time) until 
                      the end of the XIX Century.
 
 Musical theory comprises of all discoveries 
                      that were put into books and apostilles. It 
                      is not like science, which never ends.Many 
                      musicians belive that all musical discoveries have been 
                      made; However when the manipulation of mathomatics new music 
                      can be created using past findings.
 Many musicians have 
                      tried to make new discoveries,but, 
                      universities with musical 
                      programs have failed. Cado is 
                      a forerunner in Brazilian Pop/Jazz style, 
                      which combines pop music sound, improvisations of Jazz and 
                      Brazil's best rhythms like samba and baião.  
                      
 When Cado brought out his compositions and 
                      arrangements in the 90's, in Rio de Janeiro, not only did 
                      he conquer the cream of Brazilian jazz, but he 
                      also influence in the musical scene.
 
 
 Considering the musicians who work with hybrid harmonies 
                      (Chick Corea, Quincy Jones, Weather Report, etc.), none 
                      have  used second voices so far, as they 
                      would inevitably get the tierce (note which defines whether 
                      the chord is major or minor). People, as well as schools 
                      and universities always thought that hybrid harmonies were 
                      not for second voices. Now, this thought can 
                      change.
 
 When Cado was 20 years old, he developed a technique to 
                      solve this problem, using second voices in hybrids.
 
 Before talking about how to use second voices in hybrids, 
                      it is important to define  second voices.
 
 Obviously, musician will choose which interval they will 
                      use. The 8th , The 5th and unison intervals should not be 
                      used because they tend to disappear. The 9ths ,4ths   
                      and 7ths intervals should not be used because 10ths (one 
                      eight above tierces) and the 6ths are better. 
                      When they are adapted to a chord,( it will be 10 minor, 
                      10 major, 6 minor or 6 natural.)
 
 Therefore, they will be less sharps. When the musician chooses 
                      a fixed interval, he might consider using 10 
                      minor or 6 natural, for they are the best. This intervals 
                      are sharper, but there is no problem using 
                      them. The 10th interval has a beautiful effect 
                      when played by piano and together 
                      flute. The same applies to the 6ths in the 
                      bass and the guitar, but the results are awful when the 
                      guitar and the trumpet play together. Other 
                      instrumental combination should 
                      be explored too.
 
 
 
                    Seconds in hybrids
 
 First, we should choose where to 
                      place the second voice. It is usually placed at 
                      the last part of the arrangement before the song is over. 
                      One can observe which note 
                      the main melody does not get and which is the interval when 
                      the second voice is in the tierce while that note is being 
                      played. Afterwards, we would want to use 
                      this interval, for the tierce will never appear in the second 
                      voice, as the main melody does not get this melody (when 
                      it is adapted to the chord), as well as 1 and 9 flat (when 
                      it is 6th natural). If we choose the 10th interval, the 
                      note will be 5 (when it in adapted) or 5 and 11 sharp (when 
                      it is 10th minor).
 
 
 Which chords to choose:
 
 
 
                       We can change this hybrid chord 
                        to a common chord, that is because we know that if we 
                        mix the harmony with common and hybrid 
                        chords, it won't change very much hybrid sounds of harmonies 
                        with only hybrid chords. Most of those kind of music, 
                        the harmony use to already be mixed together 
                        hybrid and common chords. 
                       We can change the hybrid chord to a common chord 
                        and play it quarter.There is a very good relationship 
                        between quarters and hybrid sounds. 
                       We can choose another hybrid 
                        chord. 
                       We can choose another chord.It can be common 
                        and you may choose if play it quarter or not. 
                     
 It is important to bear in mind that in modern music, composition 
                    and arrangement combine themselves ( i.e., 
                    composition is arrangement and vice versa.) Considering this 
                    concept, it is important to know the second voice is and where 
                    it will be placed in the moment of musical composition ( 
                    i.e., composing and harmonizing already thinking about the 
                    second voice.)
 
 No arrangement maker/composer 
                    will be complete without using second voice and hybrids.
 
 The last related musical discovery -the Multi Tonic System 
                    - was made in 1903. This is symmetry and is used 
                    nowadays by Hermeto Paschoal, Quincy Jones, Chick Corea Electric 
                    Band, Wayne Shorter, Egberto Gismonti and by other jazz artists. 
                    Orchestras in the first half of the XX Century also used it.
 
 Present day musicians have tried to revolutionize 
                    musical course-plans. For example, 
                    Hermeto Paschoal's Som da Aura (Aura's Sound)(making arrangements 
                    for human speech melodies), Pat Metheny's CD Zero Tolerance 
                    For Silence (playing melodies and harmonies by loosening the 
                    strings), and Chick Corea (composing songs that are only conventions, 
                    with chords in the middle). In the first half of the XX Century, 
                    although using contemporary composition techniques (techniques 
                    aimsd at people's cognition,not at beauty), 
                    musicians tried with non-conventional scales 
                    (mere combination of scales that already existed). They also 
                    tried to escape tonality by means of fugues (they sound as 
                    tonal as any chromatic), dodecaphonic melodies, which try 
                    to dissentail from tonality by playing all the 12 notes, without 
                    repeating them (there is always an obvious tonal relation 
                    with a 3rd and 5th ,from a note to another),etc.
 
 The degree of sophistication of the work of Cado 
                    is incredibly great, both in harmony and in melody, furthermore, 
                    it is of an undescribable beauty.
 
 After we had heard so much about musical theory, people 
                    might think that this is music 
                    only for musicians, but, in fact, Cado's pieces of work attract 
                    people endowed with a good cultural background 
                    and a sensitivity to appreciate such  
                    enlightenment.
