\"\"<\/figure>\n\n

In overtone singing, the choice of the fundamental note is a structural decision that determines which harmonics will actually be available, how audible they will be, and to what extent they can be selected melodically with precision. In the practice inspired by the Tuvan tradition, the ability to make the 8th, 9th, 10th, and 12th harmonics\u2014in particular\u2014clearly perceptible and musically controllable depends on the pitch of the fundamental note\u2014ideally between G2 and G3\u2014and on good overtone singing technique<\/a>, consistent with the singer\u2019s physiological capabilities.In Tuvan kh\u00f6\u00f6mei<\/a>, a stable fundamental note is maintained, and by modifying the shape of the vocal tract, certain harmonics in the series are selectively amplified, transforming them into a true melodic line superimposed on the drone. Specifically, the Tuvan tradition is based primarily on the pentatonic scale<\/a>, which, in the harmonic series, can be replicated using only the 6th, 8th, 9th, 10th, 12th, and 13th harmonics; Tuvan masters emphasize the importance of using, first and foremost, the harmonics 8, 9, 10, and 12<\/a>, as they are well-suited for constructing immediately recognizable melodic patterns, while 7 and 11 should be avoided because they are less compatible with the pentatonic structure typical of their traditional music.From an acoustic standpoint, lowering the fundamental note makes the higher harmonics more accessible, placing them in a frequency range that is often more favorable in terms of control and perception. For this reason, the Tuvan practice places the fundamental note in a relatively low range, often between the notes C3 and G3 \u2014 130\/200 Hz, below middle C, which is approximately 262 Hz \u2014 , noting that lower fundamentals make it easier to perceive the higher harmonics, while higher fundamentals can compress the usable range and make it more difficult to select the desired melodic range, and may even prevent the selection of the 12th harmonic, which is particularly important for Tuva\u2019s distinctive sounds and melodies.<\/p>\n\n

<\/p>\n\n

Fundamental Pitch and traditionally required overtones<\/h2>\n\n

If the goal is to achieve an overtone singing similar to the most recognizable Tuvan styles, it is definitely not enough to simply \u201cproduce a whistle\u201d: one must have well-separated harmonics that are stable enough to be in tune and strong enough to be distinguished as independent pitches. Acoustic and resonance studies show that this occurs through a very narrow focusing of spectral energy, often described as a clustering of formants that selectively amplifies a harmonic region, making the chosen partial audible as a voice in its own right: hence, \u201cdiphonic effect.\u201dIn practical terms, the starting note must allow harmonics 8, 9, 10, and 12 to fall within a range where the singer can produce them with smooth articulation. If the fundamental pitch is too high relative to the singer\u2019s physiological capabilities, those same harmonics rise into a region that can become less stable, more subtle, more difficult to center, and also less rich in contrast with the drone, especially in guttural timbres such as the Tuvan kargyraa\/Sardinian bassu and the Tuvan kh\u00f6\u00f6mei\/Sardinian contra.<\/p>\n\n

\u2022 High fundamental pitch and technical difficulties<\/h2>\n\n

For a singer whose voice is physiologically higher than average, developing a diphonic singing technique faithful to the typical stylistic features of the Tuvan\/Sardinian tradition can be more complex\u2014not because the voice is \u201cless suitable\u201d in absolute terms, but because its harmonics will naturally be less intense.<\/p>\n\n

\"Fundamental<\/figure>\n\n

Let’s take an example: if the bass part of Sardinian Tenore singing is normally performed on the notes F3 and G3, a high-pitched voice might already be at the lower limit of its range on these notes; consequently, when singing these notes, it may lack the harmonic richness that a deeper voice naturally possesses, since for that voice, the notes F3 and G3 fall within the middle or even mid-to-high register. This explains why, for the same note, it is more difficult for some voices to produce a drone rich enough in harmonics and, in the case of Tuvan styles, to keep the 8th, 9th, 10th, and 12th harmonics clearly distinguishable as separate notes\u2014especially in the early stages of learning.The difficulty lies not only in hearing but also in articulation: higher harmonics require very subtle adjustments of the tongue, the front and back cavities, and the lip opening, and these adjustments become less precise as the margin for error narrows. In other words, singers starting with a higher voice may find themselves having to develop extreme precision in their vocal placement sooner than expected to achieve results that would emerge more easily with a lower fundamental note. On the other hand, when selecting lower harmonics\u2014such as the 3rd through 8th\u2014choosing a high fundamental is far more advantageous than a low fundamental, since in this case those harmonics will resonate much more strongly than the same harmonics from a fundamental an octave lower. The most striking example is middle C, which in a high voice sounds smooth, powerful, and relaxed, while in a low voice it may not be as pleasant\u2014instead sounding strained and \u201cat the limit,\u201d or \u201cflat\u201d if produced using the m2 laryngeal mechanism. But while it is almost impossible to articulate harmonics beyond the 10th in a pleasant diphonic manner with middle C, with a C an octave lower it is extremely easy to manage not only harmonics up to the 12th, but also up to the 16th or 20th.<\/p>\n\n

\u2022 Replicating a Low\/High Note<\/h2>\n\n

When replicating a note, two scenarios may arise: in the first, if the person singing the note has a voice that is physiologically similar to that of the person attempting to replicate it, it is highly likely that the replication will be faithful in terms of both pitch and timbre. But what if there is a significant difference between the two voices? Someone with a naturally lower voice, when attempting to directly imitate a higher-pitched voice, may end up producing not the same absolute pitch, but the note one octave lower.<\/p>\n\n

\"\"<\/figure>\n\n

This phenomenon is in line with the fact that, in singing and pitch matching, the vocal system often tends to seek a solution compatible with its usual state, preserving the pitch class relationship but transposing it to the most accessible register. This same phenomenon also occurs in the opposite case\u2014that is, when a high voice, in an attempt to imitate a low voice, may end up producing a note in the immediately higher octave. In short, timbre imitation takes precedence over pitch imitation, and this makes perfect sense when we consider that timbre can be imitated in various ways, whereas pitch\u2014especially low pitches\u2014is not always physically accessible.This limitation is particularly evident in tenor singing, where the \u201ccontra\u201d voice traditionally requires a voice that can be placed (roughly) between the notes C3<\/sub> and D3<\/sub>, which are sometimes notes that are out of reach for high voices, and other times they are simply at the very limit of the vocal range, therefore lacking in tonal power and intensity in the harmonic spectrum. This can lead to a significant pedagogical misunderstanding: the singer feels that they are replicating the model, but the harmonics cannot be made more powerful even with perfect technique.In Tuvan overtone singing, however, the situation is slightly more complex: the singer with the higher voice perceives an intervalic or timbral resemblance, but in reality has shifted the fundamental note by one octave upward and therefore does not have access to the same range of harmonics that the reference model previously produced. Consequently, even when the imitation seems successful from a general perceptual standpoint, the actual map of selectable harmonics no longer matches that of the reference voice.If the teacher gives and example in D33 <\/sub>and the student responds with the note D44 <\/sub>, the harmonic overtones will not match and the melodies between overtones 8th and 12th (in the key of D)4 <\/sub>won’t be possiblei. At this point, what should be done? Is it ok to force the student to sing the lower D3 <\/sub>with the risk that such note might not be physically possible? Or is it appropriate for the teacher to try to provide a more nuanced example\u2014and thus one closer to the student\u2019s vocal range? What if the teacher is unable to, or unaware of, the importance of finding strategies that are helpful to the student who is trying to learn? Personally, I believe that teaching is the only way out of what may have contributed to creating the barriers and taboos that persisted in Tuva until they finally dissolved at the end of the 20th century, but this is merely my own personal assumption. <\/p>\n\n

<\/p>\n\n

Lateralization and Control of the Fundamental Frequency<\/h2>\n\n

These difficulties can be better understood by incorporating findings from musical neuroscience. A study published in *Science* in 2020 showed that the brain significantly separates the processing of temporal information\u2014which is predominantly left-brain\u2014from that of frequency or spectral information\u2014which is predominantly right-brain. This distinction is particularly relevant in overtone singing, where the singer must simultaneously sustain a fundamental tone that remains stable over time and control an extremely fine selection of spectral content.<\/p>\n\n

\"\"<\/figure>\n\n

Regarding the perception of pitch, classic data from Robert Zatorre\u2014one of the world\u2019s leading neuroscientists in the fields of auditory cognition and the neuroscience of music\u2014and his colleagues show that discriminating variations in pitch activates the right prefrontal cortex, consistent with greater right-hemispheric specialization for certain aspects of melodic perception. However, when moving from perception to production, the picture becomes more complicated: a 2013 study linked activation of the left hemisphere to greater accuracy in vocal pitch matching, suggesting that active pitch replication relies significantly on left-hemispheric mechanisms of analysis and feedback.Further evidence comes from recent studies on speech and song production, which suggest that the production of sung words relies on the linguistic network of the left hemisphere, while melody and rhythm show a relatively greater involvement of the right hemisphere. As applied to overtone singing, this means that the choice of the fundamental note and the control of its stability depend not only on a general sense of musical ear, but on a dynamic balance between the perception of the spectral profile, motor control of pitch, and the ability to compare the internal sound with the produced sound. <\/p>\n\n

\u2022 Timbre, spectrum, and focused harmonics<\/h2>\n\n

The hypothesis that timbre primarily involves the right hemisphere is supported by an extensive body of literature on complex spectral analysis. In fact, the right auditory regions show a particular sensitivity to pitch events and rich harmonic structures, which helps explain why, in diphonic singing, the recognition and replication of the \u201cquality\u201d of the model sound do not always coincide with the exact replication of the fundamental note.<\/p>\n\n

\"\"<\/figure>\n\n

For a practitioner, this has a concrete pedagogical implication: it is possible to imitate the timbre, brilliance, or spectral character of a reference voice without actually reproducing its exact frequency profile. The risk is greatest in extreme cases\u2014that is, with very high-pitched and very low-pitched voices\u2014where the system tends to prioritize a physiologically efficient solution over absolute frequency matching. In diphonic and guttural singing, a decisive cultural\/stylistic factor comes into play: if both the timbral richness and the required pitch are not replicated, there is no alignment with tradition.Let\u2019s look at some concrete examples. A Tuvan sygyt performed with a \u201cclean\u201d voice\u2014even if it selects the harmonics required by Tuvan tradition\u2014is NOT considered a \u201csygyt.\u201d Even a sygyt performed with the correct timbre but without selecting the right harmonics, or on a fundamental that is too high or too low, is NOT considered a \u201csygyt.\u201d Tuvan Kargyraa is not considered such if the false strings do not resonate at the sub-octave below the fundamental note of the vocal cords. In Sardinian singing, the \u201cbassu\u201d and \u201ccontra\u201d voices are not acceptable if the timbre is \u201cclean\u201d rather than guttural, or if it is not sufficiently audible.<\/p>\n\n

<\/p>\n\n

\u2022 The Impact of Musical Experience<\/h2>\n\n

Experience further shapes the picture. Neuroscientific reviews indicate that experienced musicians tend to engage left-hemisphere systems more extensively in musical analysis, while non-musicians more often rely on global strategies and right-hemisphere dominance. This is relevant to overtone singing because advanced learning requires both a holistic sensitivity to timbre and a progressive, conscious analysis of the relationships between the fundamental, selectable harmonics, and articulatory adjustments.<\/p>\n\n

\"\"<\/figure>\n\n

In essence, effective pedagogy must help the student recognize which personal fundamental makes the harmonics\u2014both in their timbral and melodic roles\u2014required by tradition available in a realistic and sustainable way. Only after this choice has been made does it make sense to refine the melodic control of the 8th, 9th, 10th, and 12th harmonics, avoiding both the mistake of high voices chasing harmonics that are too high for their natural range and that of low voices which, in an attempt to imitate high-pitched models, systematically slip down to the lower octave.In conclusion, the traditions of throat singing have survived for centuries even though these studies in acoustic physics and neuroscience have only emerged very recently; nevertheless, they are fundamental because they help preserve the integrity of all those extremely specific stylistic elements that have been passed down orally until now, but which the frenzy of modern life sometimes puts \u201cat risk of being lost\u201d: just consider how easy it is to publish a video or an article titled \u201ctraditional xyz singing,\u201d and how, almost never, do these audiovisual materials truly remain faithful to the tradition they intend to convey and represent.Just consider how, years ago, a study on kargyraa was published that emphasized the need to vibrate the arytenoid caps, since the singer analyzed in the study performed it \u201cin his own way\u201d, leave alone the fact that it was a case study. Years later, other studies emerged<\/a>, conducted by analyzing the vocal tracts of highly skilled singers (of Tuvan origin), which revealed that to perform kargyraa <\/a>correctly, the arytenoid caps must NOT be involved. Nevertheless, the idea that the arytenoid caps are involved in the kargyraa technique is still around.<\/em><\/p>\n\n

Science and education should be viewed today as essential allies in the protection of the beauty that has been handed down and preserved by past generations\u2014generations who certainly led less hectic lives than we do, but whose lives allowed for greater contemplation of the world around them.<\/p>\n\n
