Tuning Musicians Before Electronic Tuners: A Historical Perspective

Before the advent of electronic tuners, musicians had to rely on their ears and various traditional methods to ensure that their instruments were in tune. This article explores the techniques used by musicians to tune their instruments, focusing particularly on pianos and other string instruments, before the implementation of precise electronic tuning references.

Historical Development of Tuning

The concept of absolute pitch references did not develop until the 20th century, and for much of history, musicians relied on local or relative pitch references. Since the 18th century, the tuning fork has been a portable and widely used pitch reference. However, how to set the tuning fork pitch initially was more informal and required the skills of experienced musicians.

The Role of Tuning Forks

The tuning fork, invented around 1711 by John Shore, became a standard tool for musicians. It produces a pure tone with few overtones, making it an ideal reference for pitch. Despite its accuracy, setting the initial pitch of a tuning fork required informal methods. Professional musicians often used tuning forks to set the reference pitch, such as A-440 or middle C-262, and then tuned their instruments relative to this reference pitch.

Tuning a Piano

Given the complexity of tuning a piano, it is a highly skilled technical process that involves understanding different types of temperament and the sacrifices and trade-offs associated with them.

Understanding Temperament

Temperament refers to the system used for tuning intervals. The most common modern temperament is equal temperament, where each half-step is exactly one-twelfth of an octave, or the twelfth root of 2. While this system ensures that all half-steps are interchangeable and modulations sound correct, it is slightly out of tune compared to other systems like Pythagorean tuning.

The Process of Tuning a Piano

Modern piano tuners start by setting a single reference pitch, often from a tuning fork, and then tune the piano in octaves, which are slightly stretched to accommodate cumulative errors. They check and adjust chords on all twelve tones, making additional adjustments as needed until the piano is in equal temperament. This process is almost entirely done by ear and requires a high level of skill.

Tuning Other String Instruments

The tuning process for string instruments like violins and guitars involves setting one string to the correct pitch and then tuning the other strings relative to it. For pianists, this process is extended to twelve strings, making it more complex.

Practical Examples and Adjustments

For fretless instruments like violins, musicians remember the positions of frets, and small adjustments can be made using mini-tuners near the bridge. This requires a keen sense of relative pitch and a good memory of the ideal pitches.

In summary, before the invention of electronic tuners, musicians relied on their ears and various traditional methods to ensure that their instruments were in tune. The tuning fork was a significant advancement, but the initial setting of its pitch was often spontaneous. Professional musicians developed sophisticated techniques for tuning pianos and other string instruments, ensuring that even complex instruments like pianos could be tuned to an accurate and consistent pitch.
