A jazz standard - most often a popular song, less often an instrumental piece - is used by a jazz musician as the basis for individual or ensemble arrangements, in a spontaneous music-making setting or in a recording studio.</p>\n\n  \n\n<p>Jazz standards, these are tunes that everyone knows and that have become classics of jazz music. Let's take a look at one of the jazz standards, the composition Now's the Time by Charlie Parker.</p>\n\n  \n\n<p>Charlie Parker is one of the few musicians who radically influenced the development of jazz, the greatest saxophonist of all time. Together with trumpeter Dizzy Gillespie and pianist Bud Powell, Parker (nicknamed Yardbird or Bird) is considered the pioneer of bebop. As a performer, Parker possessed a unique sound, an unusually developed harmonic ear and an amazing phraseological logic. In the 50s of the last century it was already impossible to play modern jazz without taking into account Parker's achievements.</p>\n\n  \n\n<figure class = \"pic\">\n    <img src = \"https://pavelgvozdev.ru/ogs_tournament/jazz_standards/Portrait_of_Charlie_Parker_in_1947.jpg\" width=500>\n    <figcaption>Portrait of Charlie Parker in 1947</figcaption>\n</figure>\n \n\n<p>Now's the Time. The theme was written in 1945. It is a blues based on simple repetitive riffs. Parker decided to use a simple intonation pattern that was always favored by musicians in his hometown, Kansas City. The first recording featured trumpeter Miles Davis, Dizzy Gillespie (playing piano), and double bassist Curley Russell and drummer Max Roach. So let's listen to the jazz standard Now's the Time.</p>\n\n  \n\n<video src=\"https://www.youtube.com/watch?v=ryNtmkfeJk4\" controls></video>\n\n<embed src=\"https://www.youtube.com/watch?v=ryNtmkfeJk4\" width=480 height=270></embed>\n\n<p>\n    If you can't see the video on the page use this\n    <a href=\"https://www.youtube.com/watch?v=ryNtmkfeJk4\">link</a> to access it.\n</p>\n  \n\n<p>There will be no scandals, intrigue or investigations at this tournament. We want calm, peace and goodness, although it never happens like this anywhere.</p>\n\n  \n\n<p>And now about pleasant things, about prizes! First of all, each participant of this unofficial tournament will receive an unofficial prize - a Chinese Go book in electronic form. The link to the book will be posted in the tournament chat for a few days after the tournament starts. Since the chat room is periodically cleared of messages, the link will be removed after some time. If you haven't had a chance to download the book, post in the tournament chat and I'll post the link again.</p>\n\n  \n\n<p>Second, GoMagic.org has generously sponsored prizes for participants of the unofficial tournaments that I host.These prizes come in the form of coupons, which can be used towards the purchase of GoMagic courses and memberships. In each group of our the third round, participants ranking 1st and 2nd will be awarded these valuable prizes.As the host, I will personally deliver the coupons to the winners via private message on OGS</p>\n\n  \n\n<p>Something about the regulations. Please note that each move adds 1 day to the time, but no more than 3 days. Time is suspended for the weekend. This means that you have to make one move per day.</p>\n\n  \n\n<p>\n\n    Regards,<br>\n\n    Grandpa Frog.\n\n</p>\n\n<a href=\"https://info.flagcounter.com/qmvB\"><img src=\"https://s11.flagcounter.com/count2/qmvB/bg_FFFFFF/txt_000000/border_CCCCCC/columns_5/maxflags_20/viewers_0/labels_0/pageviews_0/flags_0/percent_0/\" alt=\"Flag Counter\" border=\"0\"></a>\n\n\n<p>P.S. <strike>James Bond will return in the movie \"From Russia with love\"~~</strike></p>\n\n<p>Tournaments <a href=\"https://Go magic.org \">Go Magic</a> will continue in October with the \"Boldinskaya Autumn\" tournament.</p>",
