Timbre is determined by an instrument’s shape (<em>e.g.,</em> the conical or cylindrical pipe of a wind instrument), by the <a href="https://www.britannica.com/science/frequency-physics" class="md-crosslink autoxref " data-show-preview="true">frequency</a> range within which the instrument can produce overtones, and by the <a href="https://www.britannica.com/science/envelope-sound" class="md-crosslink autoxref " data-show-preview="true">envelope</a> of the instrument’s sound. The timbre of spoken vowels or of a <a href="https://www.britannica.com/art/singing" class="md-crosslink autoxref " data-show-preview="true">singing</a> voice is modified by constricting or opening various parts of the vocal tract, such as the lips, tongue, or throat.</p><a class="link-module shadow-sm d-block qa-quiz-module" href="/quiz/sound-check-musical-vocabulary-quiz" data-link-module-iframe-link=""> <img loading="lazy" src="https://cdn.britannica.com/30/254330-131-1B200240/young-girl-playing-trumpet.jpg" alt="Young girl wearing a demin jacket playing the trumpet (child, musical instruments, Asian ethnicity)" class="rounded-sm mr-15" width="70" /> <div class="line-clamp clamp-5"> <div class="module-title bg-green">Britannica Quiz</div> <div class="font-weight-semi-bold mt-5">Sound Check: Musical Vocabulary Quiz</div> </div> </a><span class="marker MOD3 mod-inline"></span></section> <span class="md-signature">This article was most recently revised and updated by <a href="/editor/William-L-Hosch/6481">William L.
