[lilypond-es] problemas al crear un documento musical

[Juan Bello]

bueno, tengo muchisimas dudas al respecto.. porque no me he encontrado
con algo así antes. lo ideal es que tengo un texto con una
explicación, tengo unos pentagramas, luego una sección un un título,
más texto y otro pentagrama. Voy a presentar un documento tal cual lo
tengo, porque realmente ya busqué y busqué y no he logrado dar con el
errors. Las casillas aparecen corridas, y el título de la segunda
sección no me aparece bien posicionado ni centrado. no se que hacer,
agradezco cualquier sugerencia ETC .

\wordwrap { Here's a classic "pseudo-jazz" vamp that artists like Van
Morrison and the Doors were quite fond of.  First, look at the key
signature: it's G major. Next, notice that the bass is playing fifths
outlining Am and Bm. The tonal center is really Am.  That makes this a
minor vamp built on the second degree of a major scale; in other
words, an A Dorian vamp (think of it as A minor with a major 6th
degree, F \sharp ).
 Get comfortable with the bass line first, it's the foundation of the
groove. Then add the "anticipated" chords, and play them with a light
touch.  The right hand fills out the harmony with three-note voicings
of minor sevenths, then the idea is extended by moving the whole thing
down to D minor (Dm7 to Em7). } }

\markup { \wordwrap { Here's another vaguely Dorian idea. This time,
the bass plays octave roots in quarter notes while the right hand
vamps from Am to D to Am7 and then back down. The result is a melodic
"hook" over an A pedal. The whole idea is transposed, with some
modification, to F, and then the last two bars make a turnaround
ending on a V7 chord (E7).
