Rock music is traditionally built on a foundation of simple unsyncopated rhythms in a 4/4 meter, with a repetitive snare drum back beat on beats two and four. Melodies are often derived from older musical modes, including the Dorian and Mixolydian, as well as major and minor modes. Harmonies range from the common triad to parallel fourths and fifths and dissonant harmonic progressions. Rock songs from the mid-1960s onwards often used the verse-chorus structure derived from blues and folk music, but there has been considerable variation from this model."
That's about as close as I can get to defining Rock. To define Rock in it's purest sense, IMHO is to attempt to remove all the sub-genres from it such as Blues-Rock, Prog-Rock, Metal, Etc. which is darn near impossible, but if you narrow it down to the definition shown above and take away the rules of all the genres you are left with just plain "Rock". Understand that this is just my opinion, and is also my poor attempt to define what is basically impossible to define, but that's how I came up with "Born To Be Wild". I'd be interested in anyone else's definition of "Rock"
Thanks for not falling asleep!:)
