by Madonna

The alto saxophone is a beloved instrument in the world of music, known for its distinctive sound and versatility. But have you ever wondered how many keys are on an alto saxophone? In this article, we will delve into the intricacies of this iconic woodwind instrument, exploring the number of keys, their functions, and how they contribute to the saxophonist’s ability to create a wide range of beautiful melodies.

The Anatomy of an Alto Saxophone

Before we discuss the number of keys on an alto saxophone, let’s first familiarize ourselves with the instrument’s basic structure. The alto saxophone, like other saxophones, consists of three main parts: the body, neck, and mouthpiece. The body of the saxophone is where you’ll find most of the keys and mechanisms that produce the notes.


The neck connects the mouthpiece to the body, allowing the player to produce sound by blowing air through the instrument. The mouthpiece contains the reed, which vibrates when air is blown over it, creating sound.


Number of Keys on an Alto Saxophone

An alto saxophone typically has 23 keys. These keys serve various functions in manipulating the instrument’s sound and producing different notes. To better understand the distribution and purpose of these keys, we can categorize them into key groups:


1. The Main Key Stack:

The main key stack is the heart of the saxophone’s key system. It includes keys for producing the fundamental notes and consists of the following keys:

a. Front F Key: This key, located on the front of the saxophone, is used to play the F natural note. It is operated by the left-hand index finger.

b. Palm Keys (D, D#, E, and F#): These keys are operated by the left-hand palm. They are essential for playing the higher register of the saxophone and for producing notes such as D, D#, E, and F#.

c. Octave Key: The octave key is operated by the left-hand thumb. When pressed, it changes the airflow within the saxophone, allowing the player to reach the higher octave of notes.

d. Side Bb Key: The side Bb key is located on the side of the alto saxophone and is used to play the Bb note. It’s operated by the left-hand index finger.

e. Front E Key: This key, located on the front of the saxophone, is used to play the E natural note. It is operated by the left-hand index finger.

f. Front High F# Key: Some alto saxophones come with an additional key that allows players to access the high F# note more easily. This key is operated by the left-hand index finger.

2. The Right Hand Keys:

The right hand of the saxophonist is responsible for controlling several keys, including:

a. Right Hand Palm Keys (G, G#, A, and Bb): Similar to the left-hand palm keys, these keys help in producing higher notes such as G, G#, A, and Bb.

b. Right Hand Pinky Keys (C, C#, and B): The right-hand pinky keys enable the saxophonist to play the low C, C#, and B notes. These keys are located at the bottom of the saxophone and are operated by the right-hand pinky finger.

3. The Table Keys:

The table keys refer to the keys located on the table (the flat surface where the player’s fingers rest) of the saxophone. These keys are operated by the fingers of both hands and include:

a. Left Hand F Key: This key is used to play the F note. It is operated by the left-hand index finger.

b. Left Hand E♭ Key: The left-hand E♭ key is used for playing the E♭ note and is operated by the left-hand middle finger.

c. Left Hand D Key: This key is responsible for playing the D note and is operated by the left-hand ring finger.

d. Left Hand C Key: The left-hand C key produces the low C note and is operated by the left-hand pinky finger.

e. Right Hand F# Key: This key is used to play the F# note and is operated by the right-hand middle finger.

4. Additional Keys:

In addition to the essential keys mentioned above, some alto saxophones come equipped with extra keys to enhance functionality, such as:

a. High F# Key: Similar to the front high F# key, the high F# key allows for easier access to the high F# note, offering an alternative fingering option.

b. High G Key: The high G key facilitates the playing of the high G note, contributing to the saxophonist’s ability to execute melodies in the upper register.

The Importance of Key Placement and Ergonomics

The placement of keys on an alto saxophone is carefully designed to accommodate the saxophonist’s hand positions and finger reach. The ergonomics of the instrument are crucial to ensure ease of playability and fluidity in transitioning between notes.

Saxophonists often emphasize the importance of comfort and ease when selecting an instrument. The key layout should allow for quick and precise finger movements, minimizing the effort required to switch between different keys and produce various notes. This ergonomic design contributes to the saxophonist’s ability to execute complex melodies and achieve a smooth and expressive performance.
