Step-by-step explanation:
Around 1950, many composers began to accompany their films with electronic sounds. This was the beginning of a significant shift in the soundscapes of film music, diverging from earlier traditional orchestral compositions. The paradigm in music was vastly transforming during this time, with the combination of electric instruments with the sounds of gospel, blues, country, jazz, and R&B giving rise to the new sound of rock and roll. While folk music plays a crucial tradition and has a heavy influence based on local conditions and ethnicities, in the context of film scores, the use of electronic music marked a new era in the audial dimension of storytelling.
