Denna studie bygger på huvudfrågan: Har musiken i grundskolan någon påverkan på elevens inställning till musik senare i livet? Under studien har nya infallsvinklar tagit form och lett studien till resultatet: Musiklärarens påverkan. Från en relativt smal syn på musikundervisningen i grundskolan har element som t ex läroplaner och ledarskapsteorier vidgat studiens syn för vad musiklärare i grundskolan har haft för styrmedel genom tiden för de fyra läroplanerna, Lgr 62, Lgr 69, Lgr 80 och Lpo 94. Denna studie kan urskilja att det har skett en progressiv utveckling av varje ny läroplan, och att lärarrollen har utvecklats med denna process.
