Or how much can beats vary and still be perceived as &#8220;equal&#8221;? We&#8217;re starting to answer such questions.\u00a0Today&#8217;s world, filled with mass-produced objects, provides a particular context for understanding regularity.<\/p>\n<p><a href=\"http:\/\/web.archive.org\/web\/20130311003301\/http:\/\/www.haskins.yale.edu\/staff\/repp.html\" target=\"_blank\">Bruno Repp<\/a> has been quantifying pianists&#8217; rhythm. In a long study of performances of the beginning of Chopin&#8217;s \u00c9tude in E Major, opus 10, number 3, Repp found remarkable similarity in the irregularities of various players.<\/p>\n<p>Olivier Senn and his colleagues have published their <a href=\"https:\/\/www.researchgate.net\/publication\/268214618_Expressive_timing_Martha_Argerich_plays_Chopin%27s_Prelude_op_284_in_E_minor\" target=\"_blank\">measurements of the micro-timings of Martha Argerich<\/a>. For example, in Argerich&#8217;s 1975 recording of Chopin&#8217;s Prelude in E Minor, within the first four-measure phrase, the shortest eighth-note lasts 452 milliseconds while the longest eighth-note lasts 807 milliseconds. Later parts of the prelude are rendered with <em>greater<\/em> extremes.<\/p>\n<p>I&#8217;d issue a caveat regarding the Argerich measurements: the recording is a studio product, and likely edited. Nothing wrong with that, except that some of these timings are the result of editing. Perfectly plausible and even beautiful timings perhaps, but not directly from the pianist. These manipulated microtimings are part of a different performance &#8212; the editor&#8217;s.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>All beats are not created equal.
