Understanding Tunings: A=440, A=415, A=392, A=466

For music performers, understanding the difference between tunings is essential, especially if they are involved in historically informed performances or working with ensembles specializing in early music. The numbers denote the frequency in Hertz (Hz).

A=440

TL;DR: Gamut violin and viola Tricolore strings are designed for A=440 tuning, as are Academie Renaissance lute, vihuela, classical guitar, and banjo strings.

A=440 (440 Hz), also known as “concert pitch,” “Stuttgart pitch,” “pitch standard,” or “modern performance practice” is the standard tuning used in most Western music today. It means that the A above middle C is tuned to 440 Hz. This standardization allows for consistency in musical performance across different instruments and ensembles.

A=415

TL;DR: Most* Gamut Academie strings are designed for Baroque instruments by those musicians playing historical performance practice at a=415 tuning, and are perfectly suitable for modern a=440 practice, but the result will be a little bit more tension at a=440. (*Academie Renaissance lute, vihuela, classical guitar, and banjo strings are designed for a=440 tuning.)

A=415 (415 Hz), on the other hand, refers to a lower pitch. It means that the A above middle C is tuned to 415 Hz. This tuning is commonly associated with historically informed performance practice, particularly music from the Baroque period and earlier. During these eras, instruments were typically tuned lower than the modern standard of A=440. Composers like Johann Sebastian Bach, George Frideric Handel, and Antonio Vivaldi wrote their music with the expectation that it would be performed at A=415 tuning.

Instrumentation: Many historical instruments, such as Baroque violins, violas, viols, and cellos, are designed to be played at A=415 tuning. These instruments often have different construction and materials compared to their modern counterparts and produce a warmer, richer sound when tuned to A=415.

Ensemble Considerations: When performing in ensembles specializing in early music, such as Baroque orchestras or chamber groups, it's common for all instruments to be tuned to A=415 to achieve stylistic coherence and authenticity. This ensures that the pitch relationships within the music remain faithful to the composer's intentions. A=415 tuning can significantly affect the tonal characteristics of music. Lower tuning can impart a mellower and more relaxed quality to the sound, which is particularly suitable for music composed before the widespread adoption of A=440 tuning standards. Performers working with A=415 tuning may need to adjust their instrument, playing techniques, and interpretations to accommodate the tonal nuances associated with this lower pitch.

Modern Applications: While A=415 tuning is primarily associated with historically informed performance practice, some modern musicians and ensembles also explore its use in contemporary contexts. Experimenting with lower tunings can offer unique sonic possibilities and artistic interpretations, even in music composed for A=440 tuning.

A=392

In addition to A=440 and A=415, another tuning standard used in Baroque music, particularly in French Baroque repertoire, is the even lower pitch A=392 (392 Hz) tuning. This tuning was prevalent during the French Baroque period, particularly in the late 17th and early 18th centuries. Composers such as Jean-Baptiste Lully, François Couperin, and Jean-Philippe Rameau wrote their music with the expectation that it would be performed at this lower pitch.

Instrumentation: Like A=415 tuning, A=392 tuning requires specific instruments or modifications to achieve the desired pitch. Instruments designed or adjusted for A=392 tuning produce a warmer and fuller sound compared to their counterparts tuned to higher pitches. Instruments may require adjustments in string tension, bridge, or bore size to accommodate A=392 tuning effectively.

Ensemble Considerations: Performing music in A=392 tuning requires a nuanced approach from musicians. The lower pitch affects not only the overall tonal quality but also the tuning of intervals and the balance between different voices or instruments within the ensemble. Musicians must adapt their playing techniques and interpretations to suit the specific characteristics of A=392 tuning, emphasizing warmth and resonance in their performances.

A=466

While A=440, A=415, and A=392 are commonly discussed tuning standards, another significant tuning standard in early music is A=466 (466 Hz), particularly associated with the Italian Renaissance period, roughly spanning the 14th to the 16th centuries. This tuning standard was used for vocal and instrumental music, including sacred and secular works by composers such as Giovanni Pierluigi da Palestrina, Josquin des Prez, and Claudio Monteverdi.

Instrumentation: Instruments in the Italian Renaissance, including strings, woodwinds, brass, and keyboards, were designed or adapted to accommodate A=466 tuning. These instruments produce a distinctive sound characteristic of Renaissance music, with a focus on clarity, purity of tone, and vocal-like expression.

Ensemble Considerations: Performing music in A=466 tuning requires careful attention to intonation and balance, as the higher pitch can affect the tuning of intervals and the overall sound of the ensemble. Musicians must adapt their playing techniques and interpretations to suit the specific characteristics of A=466 tuning, emphasizing clarity, precision, and expressiveness in their performances.

Understanding the nuances of different tuning standards — A=440, A=415, A=392, and A=466 — is essential for music performers, particularly those engaged in historically informed performances or working with ensembles specializing in early music. Each tuning standard carries unique historical and sonic characteristics that shape the interpretation and performance of music.

Hand-made in the USA by Gamut Music, Inc., a leader in the revival of early music strings and instruments. Gut strings are not intended to be used with fine tuners or string adjusters, and those devices should be removed before installing the gut string on the instrument.

All Gamut Academie strings (pure gut and gut/metal-wound) are made with beef serosa unless they specifically say “sheep gut.” All pure gut Tricolore violin and viola strings are made with sheep gut; gut/metal-wound Tricolore and all Red Diamond strings are made with beef serosa.

Gamut gut string gauges are approximate (≈) diameter. Meaning, that while a ≈0.60mm string is polished in the workshop to a diameter of 0.60mm, changes in ambient humidity, temperature, shipping, and storage conditions can cause to string to expand or contract slightly.

Gimped gut strings and custom gauged equal tension strings are gauged with the equivalent-gauge (=) system. This means that the gauge listed, such as =1.50mm, indicates that the string is approximately equal in weight to a plain gut string of that diameter. Of course, because the wire is much heavier than gut, the string will be much thinner than a plain gut string.
