Why Some Guitars Have Slanted Frets: Improving Playability and Intonation

When looking at certain guitars like the Fender Telecaster or archtop guitars, you might notice that their frets are not straight but slanted. This design decision is made for reasons that go beyond aesthetic appeal. In this article, we explore the benefits of slanted frets and why they are used in specific guitar models.

Intonation Improvement

One of the primary reasons for slanted frets is to enhance intonation. Intonation refers to the accuracy of pitch across the fretboard. By angling the frets, particularly on the lower strings, adjustments can be made to the string length, which helps ensure that notes played higher up the neck are in tune with those played open. This is vital for musicians who rely on precise intonation, especially in genres like jazz, classical, and bluegrass.

Playing Comfort

Slanted frets can also contribute to greater playing comfort and ease. The angle can facilitate more natural finger positioning and movement across the fretboard. This is particularly beneficial for complex chord formations and scales, making it easier to shift and maneuver without unnecessary strain on the hands. Many players find that this can reduce the learning curve and overall fatigue during practice sessions.

Design Aesthetics and Uniqueness

Slanted frets are also a creative choice that enhances the visual appeal and uniqueness of the instrument. This can be especially important for musicians and guitarists who want to stand out or express their personal style. By incorporating a distinct design element, these guitars become more than just musical instruments—they become works of art with a personal touch.

Compensation for String Thickness

Another practical reason for slanted frets is to compensate for string thickness. Different string gauges can affect how notes are perceived when played, especially on guitars. Slanting the frets can help bridge the difference in string lengths, ensuring that each string produces a consistent and harmonious sound. This is particularly beneficial for guitarists who play with a variety of strings or who require precise control over their tone.

Evolution of Multi-Scale Guitars

Slanted frets are not just a design feature; they are a solution to specific musical and ergonomic needs. The concept of multi-scale guitars, where each string has a different scale length, is an extension of this idea. For example, on a piano, each string is a different length, with the shortest string producing the highest note and the longest string producing the lowest. In a multi-scale guitar, the strings have different lengths, which can result in richer and more distinct sound.

Slanted frets achieve this by providing different scale lengths for each string—higher-pitched strings are shorter, while lower-pitched strings are longer. This multi-scale approach allows for a more natural and balanced response across the entire range of the instrument. Many musicians who have played multi-scale guitars, like an fanned-fret acoustic guitar, attest to the exceptional depth and clarity in their bass and treble responses. This rich sound quality is achieved without compromising on the balance and range of the instrument.

A well-known example is the fanned-fret acoustic guitar, which I played personally, and it had the most robust bass response of any guitar I've ever played. The bass was rich and powerful, yet the treble was clear and well-balanced. This unique design also impacted the guitar's overall character, making it versatile for a wide range of musical styles.

One of the most famous advocates for multi-scale guitars is renowned bassist Leland Sklar. He plays a fanned-fret bass in concert with Lyle Lovett, and he swears by his multi-scale five-string instrument. The benefits of this design are not limited to guitars; multi-scale electric basses are also gaining popularity among musicians who seek improved playability and unique tonal qualities.

In conclusion, slanted frets are a thoughtful and strategic design element that enhances playability, intonation, and overall sound quality. Whether you're a seasoned musician or a beginner, understanding the reasons behind this design can help you appreciate and fully utilize the unique capabilities of these guitars.
