position of instrument

[Stefan Thomas]

Dear lilypond-users,
in the below quoted example the position  "Trompete in B" should be higher than "con sord.". How can I change it?

changeInstrument =
#(define-music-function (parser location string) (string?)
        (make-music
                'TextScriptEvent
                'direction UP
                'text (markup #:bold (#:box string))))
       
inst = #changeInstrument % leichterer Name; nach dem "inst"-befehl einfach den Namen des Instruments in Anfuehrungszeichen angeben

{  \inst "Trompete in B"  c' ^\markup{ \italic "con sord." } }
