The saxophone is a beautifully complex instrument with a rich history, widely used in jazz, classical, rock, and pop music. One of the most intriguing aspects of the saxophone is its intricate system of keys—often referred to as “buttons” by beginners or casual players. These buttons are responsible for producing different pitches and notes by opening and closing tone holes across the instrument’s body.

In this comprehensive guide, we will explore exactly how many buttons a saxophone has, how they function, and why their layout varies across different types and models. We will also look into how a saxophonist interacts with these buttons during performance and practice.

What Are Saxophone Buttons?

When most people refer to “buttons” on a saxophone, they mean the key touches—small, round pieces of metal often covered with mother-of-pearl or plastic that the player presses to operate the key mechanism. These buttons are connected to pads that open or close tone holes on the saxophone’s body.

Each button or key is part of a mechanical lever system. Pressing one button may move several keys at once, making the system efficient and ergonomic. The buttons are designed to be responsive, allowing for quick transitions between notes.

How Many Buttons Are on a Standard Saxophone?

The number of buttons on a saxophone varies slightly depending on the model and manufacturer, but most modern saxophones—alto, tenor, soprano, and baritone—typically have between 20 to 23 main buttons. This count includes standard tone hole keys, palm keys, side keys, and pinky keys.

Here’s a breakdown of the main categories of buttons:

Main Tone Hole Keys

There are usually six main tone hole keys for the left hand (played with the index, middle, and ring fingers) and three for the right hand. These form the core of the saxophone’s playing system.

Octave Key

The octave key is located near the left thumb rest and allows the player to jump between the lower and upper registers. It functions differently from tone keys by redirecting air rather than opening a large tone hole.

Palm Keys

Most saxophones have three palm keys—high D, E, and F—that are played with the left-hand palm. These keys are critical for accessing higher notes above the normal range.

Side Keys

There are usually three side keys: high F#, E, and C. These are played with the side of the right-hand fingers and enable alternate fingerings for trills and fast passages.

Right Hand Pinky Keys

Four keys are operated by the right-hand pinky: low Eb, low C, low B, and low Bb. These are large keys located at the bottom end of the saxophone.

Left Hand Pinky Keys

The left-hand pinky operates a spatula cluster for low C#, B, and Bb. These keys are ergonomically linked for smooth transitions in the lower register.

Key Count Differences by Saxophone Type

Different types of saxophones may have slight variations in their button count due to their size, range, and role in ensembles.

Soprano Saxophone

Soprano saxophones typically have the fewest buttons, often around 20–21, because they do not usually have a low A key and their size limits mechanical complexity.

Alto and Tenor Saxophones

These are the most commonly used saxophones. They generally have between 22 and 23 buttons, including high F# and low Bb keys.

Baritone Saxophone

Baritone saxophones often feature an extra low A key, increasing their button count to about 23–24 buttons. The larger bore and extended range demand more keys.

Optional and Custom Keys

Some saxophones come with optional or custom-added keys, which can affect the total button count.

High F# Key

Not all saxophones include this key, but it’s commonly found on modern intermediate and professional models.

Front F Key

This key allows for an alternate fingering of high F, useful for faster transitions in the altissimo range.

Low A Key

Common on baritone saxophones, this key allows the player to access the very low A note below Bb.

Buttons vs Pads vs Levers: Clearing the Confusion

It’s important to note that each “button” corresponds to a pad that seals a tone hole. However, not every pad is directly under a button. Some keys are linked through levers and arms so that pressing one button moves multiple pads.

This mechanical complexity ensures ergonomic playability. For example, pressing the low Bb key may also close the B, C, and Eb tone holes through a compound mechanism.

Material and Construction of Buttons

Buttons on saxophones are usually made of metal with a covering made from:

• Mother-of-pearl

• Plastic

• Synthetic shell

These materials provide grip, aesthetic appeal, and comfort during extended play. Higher-end saxophones often use genuine mother-of-pearl for a luxurious feel.

How Players Use Saxophone Buttons

Saxophonists use all ten fingers to press different combinations of buttons, often simultaneously. Mastery comes from muscle memory, efficient finger technique, and a deep understanding of fingerings.

Techniques include:

• Standard fingering for scales and melodies

• Alternate fingerings for trills and fast passages

• Overtones and altissimo techniques

• Half-holing for microtonal bends

Differences Between Student, Intermediate, and Professional Models

Student saxophones often have fewer keys to reduce complexity and cost. Intermediate models may include extras like the high F# key, while professional saxophones offer the full suite of keys and ergonomic enhancements.

Here’s a rough comparison:

Student: 20–21 buttons

Intermediate: 22–23 buttons

Professional: 23+ buttons with custom features

Conclusion

In conclusion, a saxophone typically has 20 to 23 buttons, but this can vary depending on the model, type, and customization. Each button plays a vital role in controlling pitch, dynamics, and expressiveness. Understanding the button layout and learning to operate it with precision is a cornerstone of mastering the saxophone.

Whether you’re a beginner exploring your first instrument or a professional looking to refine your technique, paying attention to the keywork—and especially the number and layout of buttons—can greatly influence your performance and musicality.

The saxophone’s buttons are more than mechanical parts—they are the gateways to its voice, capable of expressing everything from delicate whispers to bold, roaring solos.
