\version "2.19.53"
\language "english"

hold = #(define-music-function (note) (ly:music?)
     #{
       $note \breve
     #})

global = { \key c \major \omit Stem \set Score.timing = ##f }

music = { \hold b-flat'^\markup {Cantor} a' g' f' \bar "|" }

\new Staff \with {
    \remove "Time_signature_engraver" } {
        \new Voice = "mel" {\voiceOne \global \music}
}

Works here, at least for he given example.
