A musical information displaying apparatus is to display musical notes in progression along the time axis on a musical staff together with chords and words based on the respective event data contained in a music performance data file representing a musical performance. The chords are displayed at their event positions along the time axis in the open space above and nearest to the musical staff. If two adjacent chords would overlap in part when displayed at the same vertical level in view of the respective display lengths, the vertical position of the latter chord will be shifted to prevent overlapping. The character representing the root of the chord will be displayed in an enhanced font than the other characters of the chord name. Where the words are displayed in correspondence to the notes, the words are to be displayed primarily at the positions along the time axis corresponding to the notes. If two adjacent words would overlap in part when displayed in view of the respective display lengths, the horizontal position of the latter word will be adjusted to prevent overlapping. The right justification rule is also introduced.
