以前关于颤音音高的研究试图确定颤音音调的“主音高”，而不是在旋律背景下确定这些音调的调音范围。本研究以三音琶音为研究对象，探讨有颤音与无颤音时，三音琶音的可接受调音范围。每个序列中的第二个音调被调制或未调制，其初始音高是平的或尖锐的。随着每一次重复，第二音调的音高增加或减少3美分，这取决于初始音高条件。参与者指出，当他们认为第二个音是在调和走调。颤音音调的RAT比未调制的音调大约大10美分。这在很大程度上是由于较低的RAT限制，表明颤音音调的载波频率可以比未调制音调的基频平坦10美分。
PREVIOUS STUDIES ON VIBRATO PITCH HAVE attempted to determine the "principal pitch" of vibrato tones and not the range of tuning for such tones in a melodic context. This study investigates the range of acceptable tuning (RAT) for tones with and without vibrato, using repeating ascending and descending three-tone arpeggios. The second tone in each sequence was modulated or unmodulated with an initial pitch that was flat or sharp. With each repetition the pitch of the second tone increased or decreased by 3 cents depending upon the initial pitch condition. Participants indicated when they perceived the second tone to be in tune and out of tune. The RAT for vibrato tones was approximately 10 cents greater than for unmodulated tones. This is largely due to the lower RAT limit, indicating that the carrier frequency of vibrato tones can be 10 cents flatter than the fundamental frequency of an unmodulated tone.
