Kyla is exactly the kind of girl Alex could never talk to in real life. She's a gorgeous, outspoken L.A. girl who parties to forget about her absent father and depressed mother. He's a shy ballet dancer from outside San Francisco who's never been kissed. Luckily, when these sixteen-year-olds meet for the first time it's not in real life - it's in a chat room. Alex and Kyla quickly forge a friendship that's far from virtual - maybe they're even falling in love. But what happens when the soul mate you've never met moves from online to in person?
Improvise for Real is a step-by-step method that teaches you to improvise your own music through progressive exercises that anyone can do. You'll learn to understand the sounds in the music all around you. And you'll learn to express your own musical ideas exactly as you hear them in your mind. The method starts with very simple creative exercises that you can begin right away. As you progress, the method leads you on a guided tour through the entire world of modern harmony. You will be improvising your own original melodies from the very first day, and your knowledge will expand with each practice session as you explore and discover our musical system for yourself. Improvise for Real brings together creativity, ear training, music theory and physical technique into a single creative daily practice that will show you the entire path to improvisation mastery. You will learn to understand the sounds in the music all around you and to improvise with confidence over jazz standards, blues songs, pop music or any other style you would like to play. And you'll be jamming, enjoying yourself and creating your own music every step of the way. The method is open to all instruments and ability levels. The exercises are easy to understand and fun to practice. There is no sight reading required, and you don't need to know anything about music theory to begin.

If you have always dreamed of truly understanding music and being able to improvise with complete freedom on your instrument, this is the book for you
With applications in quantum field theory, general relativity and elementary particle physics, this three-volume work studies the invariance of differential operators under Lie algebras, quantum groups and superalgebras. This second volume covers quantum groups in their two main manifestations: quantum algebras and matrix quantum groups. The exposition covers both the general aspects of these and a great variety of concrete explicitly presented examples. The invariant q-difference operators are introduced mainly using representations of quantum algebras on their dual matrix quantum groups as carrier spaces. This is the first book that covers the title matter applied to quantum groups.

A cannon. A strap. A piece. A biscuit. A burner. A heater. A chopper. A gat. A hammer A tool for RULE Or, you can call it a gun. That’s what fifteen-year-old Will has shoved in the back waistband of his jeans. See, his brother Shawn was just murdered. And Will knows the rules. No crying. No snitching. Revenge. That’s where Will’s now heading, with that gun shoved in the back waistband of his jeans, the gun that was his brother’s gun. He gets on the elevator, seventh floor, stoked. He knows who he’s after. Or does he? As the elevator stops on the sixth floor, on comes Buck. Buck, Will finds out, is who gave Shawn the gun before Will took the gun. Buck tells Will to check that the gun is even loaded. And that’s when Will sees that one bullet is missing. And the only one who could have fired Shawn’s gun was Shawn. Huh. Will didn’t know that Shawn had ever actually USED his gun. Bigger huh. BUCK IS DEAD. But Buck’s in the elevator? Just as Will’s trying to think this through, the door to the next floor opens. A teenage girl gets on, waves away the smoke from Dead Buck’s cigarette. Will doesn’t know her, but she knew him. Knew. When they were eight. And stray bullets had cut through the playground, and Will had tried to cover her, but she was hit anyway, and so what she wants to know, on that fifth floor elevator stop, is, what if Will, Will with the gun shoved in the back waistband of his jeans, MISSES. And so it goes, the whole long way down, as the elevator stops on each floor, and at each stop someone connected to his brother gets on to give Will a piece to a bigger story than the one he thinks he knows. A story that might never know an END…if Will gets off that elevator. Told in short, fierce staccato narrative verse, Long Way Down is a fast and furious, dazzlingly brilliant look at teenage gun violence, as could only be told by Jason Reynolds.
This invaluable book presents most of the important papers of Emil Wolf, published over half-a-century. It covers chiefly diffraction theory (especially the analysis of the focal region), the theory of direct and inverse scattering, phase-space methods in quantum mechanics, the foundation of radiometry, phase conjugation and coherence theory. Several papers which have become classics of the optical literature are included, such as those on Wolf's rigorous formulation of the theory of partial coherence and partial polarization, the introduction of diffraction tomography, and his discovery of correlation-induced shifts of spectral lines (often called the Wolf effect). There are also papers dealing with the historical development of optics and some review articles.
