Message-ID: <14Vrt8-07wldoC@fmrl02.sul.t-online.com> Neuigkeiten aus USA: Absolute Pitch in Infant Auditory Learning: Evidence for Developmental Reorganization Jenny R. Saffran and Gregory J. Griepentrog University of Wisconsin‹Madison To what extent do infants represent the absolute pitches of complex auditory stimuli? Two experiments with 8-month-old infants examined the use of absolute and relative pitch cues in a tone-sequence statistical learning task. The results suggest that, given unsegmented stimuli that do not conform to the rules of musical composition, infants are more likely to track patterns of absolute pitches than of relative pitches. A 3rd experiment tested adults with or without musical training on the same statistical learning tasks used in the infant experiments. Unlike the infants, adult listeners relied primarily on relative pitch cues. These results suggest a shift from an initial focus on absolute pitch to the eventual dominance of relative pitch, which, it is argued, is more useful for both music and speech processing.

IF YOU'VE ever had a song in your head but don't know what it is, you'll soon be able to get the answer just by whistling to your PC. Bjørn Olstad, research and development chief at Fast Search and Transfer (FAST) in Oslo, Norway, says their new search software can find a tune and name it with as few as five notes to go on. Users can sing, whistle or play a few notes on a musical instrument into their PC's microphone. If that stretches your musical talent too far, "simply tapping a rhythm can be enough to locate the right file", says Olstad. The key to the software is its ability to digitise your ditty and then extract a sequence of pitch and timing data that can be usefully compared with actual musical pieces. The idea is that after you've entered your tune, the search engine scours a database of tunes, looking for matching pitch and timing information. "Timing is a non-precise parameter. Even a pianist cannot play a piece the same way twice. And the pitch of different singers can vary widely," says Olstad. "Our algorithm has been designed to accommodate this fuzziness." But there's another problem. At the moment there aren't any databases of relevant musical information. So FAST, which runs the search engine at www.alltheweb.com, is negotiating with other dotcoms who might want to set up commercial music databases to catalogue tracks they have for sale. Olstad sees great potential for the program--but not just for tracing half-forgotten tunes. He predicts that scholars will use it to compare compositions, and lawyers to settle copyright battles. Max Glaskin ---------- Hier die entsprechende Meldung von Bild der Wissenschaft online: Gesummt oder geklopft - Software erkennt Musikstücke sofort Wie hieß noch der letzte Sommerhit? Nur fünf Töne - gesungen, gesummt oder geklopft - benötigt eine neue Software der norwegischen Firma "Fast Search and Transfer" um Musikstücke zu erkennen. Das Programm wandelt die Rhythmen und die Töne des Vortrags in digitale Informationen um. Aus einer Datenbank sucht der "elektronische Musikkenner" dann die passende Komposition, berichtet das Wissenschafts-Magazin "New Scientist". "Schwankungen in der Geschwindigkeit und der Tonhöhe toleriert das Programm. Schließlich kann nicht einmal ein Pianist oder Sänger ein Musikstück zweimal auf die gleiche Art vortragen", erläutert Björn Olstad von "Fast Search and Transfer". Derzeit sucht das Unternehmen allerdings noch einen Partner, um eine zum Programm passende Musikdatenbank aufzubauen. Anwendungsmöglichkeiten für die Software sieht Olstad viele: Juristen können geklaute Melodien leichter aufspüren und die Urheberrechte einklagen. Musikwissenschaftlern soll die Software helfen Kompositionen auszuwerten und zu vergleichen.
