Dear Sandeep, Yes, there is an solution, hope You can use it: #(define (naturalize-pitch p) (let* ((o (ly:pitch-octave p)) (a (* 4 (ly:pitch-alteration p))) ; alteration, a, in quarter tone steps, for historical reasons (n (ly:pitch-notename p))) (cond ((and (> a 1) (or (eq? n 6) (eq? n 2))) (set! a (- a 2)) (set! n (+ n 1))) ((and (< a -1) (or (eq? n 0) (eq? n 3))) (set! a (+ a 2)) (set! n (- n 1)))) (cond ((> a 2) (set! a (- a 4)) (set! n (+ n 1))) ((< a -2) (set! a (+ a 4)) (set! n (- n 1)))) (if (< n 0) (begin (set! o (- o 1)) (set! n (+ n 7)))) (if (> n 6) (begin (set! o (+ o 1)) (set! n (- n 7)))) (ly:make-pitch o n (/ a 4))))
#(define (naturalize music) (let* ((es (ly:music-property music 'elements)) (e (ly:music-property music 'element)) (p (ly:music-property music 'pitch))) (if (pair? es) (ly:music-set-property! music 'elements (map (lambda (x) (naturalize x)) es))) (if (ly:music? e) (ly:music-set-property! music 'element (naturalize e))) (if (ly:pitch? p) (begin (set! p (naturalize-pitch p)) (ly:music-set-property! music 'pitch p))) music)) naturalizeMusic = #(define-music-function (parser location m) (ly:music?) (naturalize m)) #(define vereinfachs naturalizeMusic) %Enharmonische Verwechslung %Nur Kreuze zeigen kreuze = #(define-music-function (parser location x) (ly:music?) #{ \transpose ges fis $x #}) %nur Bes zeigen bees = #(define-music-function (parser location x) (ly:music?) #{ \transpose fis ges $x #}) meistkreuze = #(define-music-function (parser location x) (ly:music?) #{ \vereinfachs \transpose ges fis $x #}) meistbees = #(define-music-function (parser location x) (ly:music?) #{ \vereinfachs \transpose fis ges $x #}) You can use it like: \new Staff { \transpose c, c { \kreuze ges1 \bees fis \meistkreuze {c d es e fis g a b } }} Note, that it doesn't not work in relative mode. I usually use the possbilitie to expand abbreviations in Frescobaldi. I type s then <strg> <space> and then I get "\kreuze" > Hi list, > > Is there a scheme snippet that will reprint a sharp as the enharmonic > flat if it appears after a flat, reprint a flat as the enharmonic > sharp if it appears after a sharp, and leave a note alone if it > appears after a natural?
