A music teacher explaining strumming told a schoolgirl to think of the hand technique as a gesture to make to boys.
Keith Jenner had been teaching the Green Day song "Wake Me Up When September Ends" the to girl, who was in sixth year studying Advanced Higher guitar.
The former pupil, now studying to be a music teacher herself, said her background had been in classical and Spanish guitar - which involved plucking - and Jenner had been teaching her to strum so she could also play pop.
