Nadi Bumi: Extended Techniques for Alto Recorder and Science (Paper Proceeding and Presentation on 22nd November 2016, 1400-1530, Choir Room.)
Previous musical acoustic researches have defined acoustic properties of recorder fundamental techniques for sound production such as tunings, dynamics, articulations and timbres. However, the acoustic properties and extended techniques other than multiphonics of recorder especially for alto recorder are not distinctly defined, scientifically and artistically. The aims of this research paper are to: 1) study the scientific and artistic profiles of alto recorder selective conventional extended techniques sound production that exists in contemporary classical recorder music compositions and 2) discuss a newly discovered extended techniques derived from the selective conventional extended techniques which were partly used in Nadi Bumi. This paper presents the applied research on Nadi Bumi music composition derived from instrumentation study, musical ideas associated with bone whistle or flute, Fibonacci number series, Schumann Resonance and spectral music techniques. Eventually, the research led to empirical study of alto recorder conventional and new extended techniques in sound production. The present study was carried by employing narrowband short-time Fourier Transform (STFT) spectrogram analysis, absolute scale non-linear decibel loudness seismograph analysis, music composition analysis based on selected readings of contemporary recorder music composition score excerpts and its controlled audio recording environment of alto recorder sound production sampling. The study ultimately led to the exploration of new alto recorder extended techniques sound production which will be discussed at the end of the paper. Music composers are anticipated to make reference to this research framework for future development of new and alternative artistic alto recorder music compositions.
