Didjeribone: Construction, intonation and sound spectrum analysis

The study presents contemporary musical instrument Didjeribone research results. Two musical instruments with the different pipe length and the different pipe inner radius are constructed and intonated at the hromatic scale. The research has been done to achieve the simple goal of finding main characteristics of the Didjeribone musical instrument sound spectra. The results show that for low and high frequences even harmonics have higher intensity than odd harmonics in the central and upper instruments range and that odd harmonics have higher intensity than even ones for central frequences.
