Again, mahgister, sheet music was around way before Edison. Commercially available sheet music...hit songs of the time..
Again.... 😁😊
Sheet music was not ONLY and MAINLY a "commercial" business, it was a cultural necessity first to make playing family and musical education a general societal fact... The commercial aspect here are subordinated to the musical activity....
The fact that i will buy a wedding ring and a dress, does not make love a business, or a commercial sex enterprise...Internet will do it on s scale so great that it will make old prostitution business a primitive economical game ....
Like recording and vinyl albums will make music an "object" to sell more than an event...We can buy a violin or sell it too this does not make music a "commercial" affair...And someone claiming sheet music make music a business is not wrong but it extend and distort the meaning of the activity out of his limits... Music begun to be a business after recording invention...And after the development of modern marketing technique many aspects of music begin to be a consumers objects instead of being mainly a spiritual activity...
With Edison and the marketing of music playback with recording, music begin to be a product itself, an no more mainly a spiritual event ....
The musical activity here became subordinated to the commercial goals...
