Then unaccompanied guitar solos wouldn't be a music right?
Same as Solo parts of Concertos from good ol' classical music?
But rock does not need those solos to be considered rock. Rock and classical can be without these solos and still be rock/classical. Just like rap can be without harmony and still be rap.
And still be music, like the music from eastern asia and other cultures from all around the world which does NOT require all 4 elements.
I am just saying from the technical meaning of music. The rap genre is not music, although some artists add to it creating music. Music can indeed have breaking glass sounds, as they may be meant to expose a part of the melody.
Wouldn't rap be considered music then? if some of the artists decide to add harmony? that rap song with the harmony would be still classified as rap genre/music.
I mean even if the artists (like from late 70's-80's) decided not to put in "harmony"; their spoken/rapped lines (with rhythmic motives and melodic presense, which are present in all raps from all eras) plus the bass ostinatos & rhythmic/dynamic patterns can be classified as harmony imo. It just does not fit into classiscal rules of harmony. They don't/didn't even allow I-IV-V-I progressions. But seems to work fine imo.
I guess Chuck Berry, Elvis ain't no musicians techinically. Even though their music still includes all 4 parts, it cannot be a music cos of the wrong progressions. Just like rap music, it has all 4, but it's doesn't follow the rule of the traditional classical harmony etc. Therefore it cannot be music. Gregorian Chant cannot be music because their earlier forms were sung mostly monophonic.
Rap it self, like just freestyling without ANY accompaniments, if you don't consider that as a form of music/art; i must say all those guitar solos cannot be considered music either.
I guess Paganini's Caprice 5th/Eugene's trick bag would be rap.
Whew. This debate is fairly controversial.
Why didn't you ask something less controvisial, such as "is there a god?" or "are power chords real chords, because they lack a 3rd?"
Some theory teachers and Pre-Classical and Classical era of Classical music defines power chords and moving one powerchord to the next powerchord to be very very wrong and also "empty" sounding.
And there is a god, and his name is Hendrix
