Bebop scales add a single [[chromatic passing tone]] to the [[Heptatonic scale|seven-note]] major scale (Ionian and Mixolydian modes). The added passing tone creates an eight-note scale that fits rhythmically evenly within a {{music|time|4|4}} measure of 8 eighth notes, thus making it useful in practicing. When an eighth note bebop scale run starts on the beat from a chord tone (i.e. the [[Root (chord)|root]], [[Third (chord)|third]], [[Fifth (chord)|fifth]] or [[Seventh (chord)|seventh]]) the other chord notes will also fall on the beat. As a result, all of the [[Nonchord tone|nonchord tones]] will fall on [[off-beat (music)|upbeats]].

There are two commonly used types of bebop scale:

# The dominant bebop scale, which adds a chromatic passing tone between the 7th and the [[Root (chord)|root]].
#: <score sound="1"> {
\override Score.TimeSignature #'stencil = ##f
\relative c' {
  \clef treble \time 8/4
  c4^\markup { Bebop dominant scale on C } d e f g a bes b! c
} }
</score>
# The major bebop scale, which adds a chromatic passing tone between the 5th and 6th notes.
#: <score sound="1"> {
\override Score.TimeSignature #'stencil = ##f
\relative c' {
  \clef treble \time 8/4
  c4^\markup { Bebop major scale on C } d e f g gis a b c
} }
