Improvisation?

Improvisation is a common term used in music for spotaneous musical reaction. What it means basically is playing a melody on the spot over a given chord progression or situation.

So what does improvisation do to you? Well, one thing, music are written, in my opinion, out of improvisation. It also helps you(or at least to me) to improve musically, or increases your chordal sensitivity. Chords are like the background in a picture and the notes or melody over the chord progression are the garnishes and themes.

However, it's really subjective to individual taste and preferences. Some like fast notes, some like legato feels, some like clssical phrases, some prefer fewer notes, so may I ask, who is right and who is wrong? Answer is no one.

Improvisation enhances two things, one is personal style and character, the other, is composition ability.

Listen to Jazz and live music, most of the time, improvisation saves asses and/or give a new lease of life to a particular piece of music.
