Macrotone, spelled /məˈkrəʊ.tən/, is a term used in music to describe a long note or prolonged tone. The first syllable "macr-" is derived from the Greek word "makros" meaning "long," while the second syllable "-tone" refers to a sound or tone produced by a musical instrument. The spelling of Macrotone uses the combination of the letters "c" and "r" to represent the sound /kr/, while the stress falls on the second syllable, as indicated by the diacritic mark over the "o" in the IPA transcription.
