“His performance was also intensely visual, with his volatile movements in front of the piano, and his cries and wild vocal accompaniment to his playing, all of which spoke eloquently of his extraordinary passion for the instrument and the music he coaxed, tickled and sometimes pounded out of him. Many critics were put off by all this, thinking it was a mere outward show- and therefore insincere. In fact it is an essential part of music-making for Jarrett, his way of achieving his state of grace… the ecstasy of inspiration. Miles Davis understood that immediately, and so did most other musicians. Jack DeJohonette says: “The one thing that struck me about Keith, that made him stand out from other players, was that he really has a love affair with the piano, it’s a relationship with that instrument… Keith’s hands are actually quire small but because of that he can do things that a person like myself, or other pianists with normal hand spans, can’t do… it enables him to overlap certain chord sequences and do rhythmic things and contrapuntal lines and get these effects of like, four people playing the piano… But I’ve never seen anybody just have such a rapport with their instrument and know its limitations but also push them to the limits, transcend the instrument – which is what I try and do with the drums as well.”

“Jan Garbarek about Keith Jarrett:“What people don’t consider is all his wonderful ways of accompanying his own melodies. That is only that version. But I’ve played with him so many nights and they were all different!... The way he voiced things and the inner lines he played behind the melody, and his own compositions were often radically different, but no less beautiful… It’s hard to believe!”

“I had never before thought of how awful the relationship must be between the musician and his instrument. He has to fill it, this instrument, with the breath of life, his own. He has to make it do what he wants it to do. And a piano is just a piano. It's made out of so much wood and wires and little hammers and big ones, and ivory. While there's only so much you can do with it, the only way to find this out is to try; to try and make it do everything.”

“The Rolling Stone magazine: ” Jarrett… demonstrated his strengths – his sure times, his far-ranging imagination, his sharply-honed technique and his particular inner fire, which is at once steady and vulnerable. When he plays alone, Jarrett pushes his creativity to its limits. It’s almost scary to hear someone who apparently relies so totally on the spirited, flowing, almost effusive directions of his muse, yet the muse seems to never let him down.”

“Talking of his relationship with Jarrett, DeJohnette says, “I love him because, as a pianist and drummer myself, I can identify with him … the concept of what to ignore, what to leave in, what to leave out… we intuitively understand that … that’s why when we play together… we never know what’s going to happen, but we always get something happening that turns us on.”

“These solo concerts were without precedent, not only in jazz history, but also in the entire history of the piano. They were not renditions of composed music committed to memory, nor were they a series of variations on composed themes. They were attempts at very long stretches (up to an hour at a time) of total improvisation, the creation from scratch of everything: rhythms, themes, structures, harmonic sequences and textures. Before a concert, Jarrett would try to empty himself of all preconceived ideas, and then allow the music to flow through and out of him. He said that if he was not able to empty himself he would, almost invariably, have a concert that was not as good. There might be periods when he seemed to be marking time but and feeling his way into a new area, but this was also part of the total experience which delighted and enthralled audiences. The sustained intensity of Jarrett’s inspiration during these marathons was literally awesome and, almost in the sense of preacher and congregation, he seemed to want the audiences to be not only witnesses but also participators on the occasion...”

“… there’s one thing that I know well – that I feel very alone. It’s the price you have to pay if you want to be yourself. And don’t believe that I don’t suffer for it, but it seems to me that I have nothing to say to the majority of people and it’s perhaps that which makes me feel timid… I'm very demonstrative when I play. I always make faces, laugh, jump about, gesticulate, and am very animated, and many people who see me like that think that I’m much more reserved when I’ve left my piano. In reality, I feel truly at ease only in music…Keith Jarrett”
