Когда одновременно вибрируют две трубы одинаковой длины, они обе играют одну ноту. Обе выдают одинаковую основную частоту. Это самая низкая частота и, как правило, самая громкая. Но две трубы из разных материалов будут издавать разный звук, и тогда мы различим звучание двух разных инструментов.

Дело в том, что из каждой будет исходить свой набор более высоких частот. Они называются обертонами. Они тише основных частот, и мы их не различаем, но они придают звуку окраску. Это называют тембром.

По тембру мы [музыка] отличаемся. Амплитуда довольно часто обертоны музыкальных инструментов – это целые кратные основной частоты. Их называют гармониками.

Переведено и озвучено студии Верт Дайдер.
