Bebop scales were ‘created’ (or at least ‘named’) by a Jazz composer called David Baker. He called them this because he noticed many Jazz musicians from the Bebop Era (Charlie Parker, Dizzy Gillespie, Charlie Christian, Bud Powell, etc.) inserted an extra chromatic passing note when playing scalar runs. He settled on the above chromatic notes and created the above scales. However, there’s no reason to restrict yourself to these particular extra chromatic passing notes. In theory, you can add any additional chromatic passing note to a standard 7 note (Heptatonic) scale and create your own quasi-‘Bebop Scale’.
