A piano concerto is a composition in which a solo piano (or harpsichord) is accompanied by a large ensemble of other instruments (usually a full orchestra but not always). This list looks at 10 of the greatest (with an additional bonus entry from JFrater). The criteria for inclusion and ranking of entries are musical artistry, technical artistry, pianistic power, balance between piano and orchestra, and historical influence.
One of my interests include listening to modern/traditional/contemporary classical music. =) nice list by the way!
