At first we utlize the mode of playing the trombone as the post 352 that we remind below.
THE 2-DIMENSIONAL SEQUENTIAL-CONTINUOUS OVERTONES+SLIDING IMPROVISATION MODE FOR TROMBONES
In this improvisation mode, we shift from center-note to center-note in the improvisation not directly by a jump but sequentially through vertical shift-Jump (slur) in the overtones and correction by sliding the slide.
As we have mentioned elesewhere it is sufficient that at least 50% of the time the notes fits with the underlying chords for the result to be acceptable in listening. Thus the 49% of the time we may shift by overtones and sliding till we find a new center-note where we stay for much longer time.
It may be a non-thinking experimental method without realizing which notes we play.
We may start the shift for the desired direction either vertically by overtones jumps or horizontally by sliding the slide.
The horizontal dimension of the change of the pitch by the slide (6 semitones) corresponds to the ancient structure of scales of the music by tetrachords (5 semitones). The first octave of the trombone is a natural union of tetrachords joined by a whole tone (divorced tetrachords as was the ancient term)
The difference e.g. with an harp or piano or panflute is that in such improvisation we have only one dimension both geometrically and as pitch while with a trombone we have two dimensions one local geometric with the slide and one with the embouchure by overtones (partials).
HOW TO MAKE BEAUTIFULL SIMPLICIAL COUNTERMELODIES WITH AN EASY IMPROVISATIONAL WAY WITH THE TROMBONE OR A STRING INSTRUMENT WITH OVERTONE TUNING.
We remind the reader that a simplicial countermelody is a counterpoint parallel melody (that by parts 2,3,or 1st voice) with much fewer notes that the original melody , about one or twonotes per underlying chord. If it willbe at the lowest octaves it would be simpli called a bass line .
The current suggested method is based one two factors
1) W may easily jump with the intsrument a melodic (3rds) or harmonic (4ths or 5ths) interval at any time. This is so e.g, with a trombone that we shift with the embouchure among the overtones, and as usually we are either in the harmonic intervals 2nd ovtave of the overtones, or the 2nd melodic intervalsovtace of overtones. If we are in a string intrsument tuned by a set of succesive overtones e.g. troll tuning then again by shifting to the neighboring string we have the same easy effect.
2) We may easily make small chromatic intervals (of 2nds) moves. With the trombone thsi is done with the slide for a range of a 4th , 5th or half octave. For a string intrsument tuned by a set of succesive overtones this is done again easily by shifting longitudinally onthe same string.
The improvisational method of creating such beautufull simplicial counter melodies is as follows.
Modt often a melody with many notes has the majority of its intervals as chromatic interavls of 2nds and maybe some melodic (3rds) or harmonic (4ths, 5ths) intervals. But the simplicial countermelody can be more beautiful by havin the minority of the intervals as chromatic and the resy as melodic and harmonic in a way that there is strict sepration.
1) The way to do is is that when the melody is moving we saty as much as possible on thesame note on the string onthe string instriment or on the same overtone across slide range in the trombone ,and if necessary we make a small shift by in interval of semitone or tone (2nds, chromatic intervals) .
2) If this is not possible so we have an harmonically fitting countermelody or when we fell that we want to shift up or down we shift at the trombone by one or two overones up or doen and we adjust the slide to have a note that fits. Similaly with the string instrument we shift by one or two strings and we adjust across the string to find a closest note that fits.
GIVEN A MINIMUM LEAST NUMBER OF NOTES, AND STARTING FROM A NOTE FIND THE MINIMUM TOTAL LENGHT (IN SEMITONES) PATH OF NOTES THAT CONTAINS THEM AND THAT FITS THE HARMONY.
Of course the way to find such solutions of simplicial counter melodies, is e.g. by starting with a note and staying there as long as the harmony is fitting. When the harmony deviates (will deviate in general, that is why we need to know in advance the harmony of the song) for a long time, we chose to shift either up or down, which ever melodically feels better, and we slide till the first note that we find that it fits (will fit for long) the harmony. We stay there and repeat the procedure.
Obviously the result of it is a simplicial countermelody that separates the chromatic with the melodic and harmonic intervals, which is chromato-harmonic effect.
THE TROMBONE FOR EASTERN RAPSODY CONTINUOUS SIMPLICIAL COUNTERMELODIES BASED ON TETRACHORDS (E.G. FOR SIMPLICIAL COUNTER--MELODIES FOR SAITHIES, DAKTYLIES OF CRETE)
The eastern songs inherited by anciet times rapsodies ar accompanied with a single power5 chord of the type 1-5-1 and with melodies inside a 4-notes scale the tetrachord as in posts 201, 203. Such melodies when we sing them have many embelishments of a fraction of the semitone around a note. So it is hard for the male voice to sing them. But with a trombone and its slide we can do very good job!
The technique of Tommy Dorsey for the trombone is best for such contunous and smooth simplicial submelodies. E.g. here are examples of the smooth technique of Tommy Dorsey

Although there is no trombone in the next song it has such a type of eastern melody so we can listen why a trombone there with a simplicial countermelody of fewer notes and at a lower octave than the voice would fit very well like a continuous bassline.
