The task is to write music chords, on a staff, using package MusixTex.
MWE shows a way to place a note within a chord marginally to the right in case it overlaps with other ones.
Works OK when notes without sharps or flat are included in the chord (Cmaj6) but when there is an accidental (F7) it appears on the vertical axis of the chord notes.
Moreover when there is more than one accidental in the chord (Bbm7) then they align with each other.
Is there a way to adjust the distance of the accidentals from the notes, or is there another better way to write chords?
