However, it is easy to play notes which do not harmonize with other notes and pitches which are being played. Provided herein is a method, computer program product and electronic device for assigning a set of pitches to a plurality of cells of an electronic device having a touch screen input device. The method may include the steps of obtaining an input chord, disassembling the chord into at least one base note and a plurality of individual voices, arranging a predetermined number of voices of the chord according to at least one predefined rule, and assigning at least one set of pitches to a plurality of cells of an electronic device, said set of pitches corresponding to the base note and arranged predetermined number of voices of the chord. The present method allows a musician to freely play along without the possibility of playing an errant note as the user does not control the actual pitch associated with the cells being indicated by a user on the touch screen."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Grid based user interference for chord presentation on a touch screen device","description":"Improvisation or playing along with a musical group or with a song is enjoyable to people and musicians of all ability levels.
