Improvisation
It surprises me time and again how few guitar solos can be heard on the radio today. Although the guitar is probably one of the most played instruments in the world and in popular music, its presence is often overshadowed by keyboards, programming or simply doesn't exist. Over more than the last decade even rock music had most of the solos eliminated. There are a few acts that still incorporate solos in their arrangements. I have no idea why things are the way they are. Do bands skip solos to become more marketable and adhere to the "a hit song can't be longer than three and a half minutes" rule? Or is there a legion of hundreds of thousands of guitar players that can play great rhythm but no lead? It will probably remain a mystery to me. However, I do think that it is a shame because guitar solos were an integral part in the rise of rock music in the late 60's, 70's and still in the 80's. Styles that to this day enjoy the presence of guitar solos are blue...
