history: Rock and Roll is my favorite music genre, are you familiar with it? I'm aware that it is a popular genre of music and had its origins was during the late 1940s to early 1950s in the US. Yes rock and roll evolved from from African American musical styles such as gospel, blues, jazz, boogie woogie,along with country music. Sounds informative, were you also aware that classic rock and roll typically is played with 1 or 2 electric guitars? Yes, and in the earliest rock and roll styles, either the piano or saxophone was typically the lead instrument. The genre had other elements from genres before it too I believe. I agree, since rock and roll elements can be heard in 1920s blues records as well as 1930s country records. Rock and roll actually got its name in 1954. That sounds about right, I remember hearing a quote by Greg Kot about rock and roll too but can't quite remember what he said. I think you mean how he said its a type of popular music from the 1950s US? Yeah I believe so, do you know when guitars starting replacing the piano and sax in rock and roll?
knowledge: In the earliest rock and roll styles of the late 1940s and early 1950s, either the piano or saxophone was often the lead instrument, but these were generally replaced or supplemented by guitar in the middle to late 1950s.
