Saxophone Bore Size: What It Means on a Listing

What the word bore names on a saxophone listing

On a saxophone listing, the word 'bore' names the inner tube of the instrument's body: the long column of air that runs from the neck down through the bell. In general terms, the bore is the inside diameter of that tube. A listing that mentions bore is describing part of the instrument's construction, not its finish or its keywork.

The bore is one of the parts a buyer may see when reading a specification list, alongside the neck, the bell, the keys and the pads. For a quick tour of those terms, see how to read saxophone specifications.

• Bore: the inner tube of the body, in general terms.
• Neck: the curved tube that connects the mouthpiece to the body.
• Body: the main tube that holds most of the keywork.
• Bell: the flared end of the instrument.

Large bore and small bore as listing words

When a title or bullet list says 'large bore' or 'small bore', it is stating a design choice made by the maker. A large bore points to a wider inner tube; a small bore points to a narrower inner tube. Both are real differences in the instrument's shape. The catalogue does not state what either one does to the sound.

The same model can appear in several colors, and the bore is a separate detail from the finish. The finish is a look; the bore is part of the tube. For the finish side of a listing, see saxophone lacquer finish types.

What the catalogue states about a bore

The catalogue, as shown on a seller's page, gives words like 'large bore' or 'small bore' as stated details. Nothing more is stated: no decibel figures, no sound description, no comparison between bores. This site compares listings on those stated details only, and it does not add an interpretation about tone, response or projection.

The smoothness of the inner wall is a related design word. For what that term names on a listing, see saxophone bore smoothness effect.

What the catalogue does not say about sound

A reader may hope the listing will say which bore sounds better. No maker page in this site's catalogue makes that claim. The guides rank models by what the seller states: register, level, kit contents and finish. They do not rank one bore above another, and they do not claim how a bore affects tone or playability.

If you are comparing two listings, look at what each states: the register, the level word, the kit list and the finish. Those are the details this site compares. The bore, when stated, is one more stated detail, but it is not scored.

The catalogue also does not state how a bore affects resistance or response. Those qualities are outside the stated details, and no claim about them appears in the guides.

Bore size across soprano, alto, tenor and baritone

The four main saxophones in a catalogue are soprano, alto, tenor and baritone. Each has its own body size, and each has its own bore as a design value. The bore named on a soprano listing is not comparable to the bore named on a baritone listing; the two instruments are different sizes.

A curved soprano and a straight soprano share the same register but have different body shapes; the listing may state a bore for either one. For the shape question, see soprano straight vs curved saxophone.

For a first decision, choose the register before comparing details like the bore. See alto or tenor first.

How to read a listing that mentions bore

When a listing states a bore, read it as one stated fact. Put it beside the other stated facts: the register, the level, the kit contents, the finish. A bore word alone does not tell you whether the instrument suits your budget or your plans.

If the listing does not mention a bore, that detail is simply not stated by the seller. This site does not guess it. The guides list what the seller states and leave the rest aside.

The main saxophone guide explains how the ordering rule works: best saxophone.

• Register first: soprano, alto, tenor or baritone.
• Level word next: student, intermediate or professional.
• Kit list, then finish.
• Bore only if the seller states it.

Bore and the buying decision

For a buyer, the bore is worth reading when it appears, but it should not be the first filter. The first filter is the register: does the listing name a soprano, alto, tenor or baritone? The second filter is the level word: student, intermediate or professional. The third filter is the kit: what does the box list? The bore, when stated, is a construction detail that may or may not be part of the seller's pitch.

This site does not state that a large bore is better for jazz or a small bore is better for classical. No guide here makes a musical recommendation tied to bore size. The guides compare what the seller states, and they leave the sound to the player, the mouthpiece and the reed.

If you are picking a mouthpiece later, the bore of the instrument is not a mouthpiece specification. The mouthpiece has its own facing and chamber, which are separate listing words. See saxophone mouthpiece chamber volume and saxophone mouthpiece facing length for that side of the search.

• First choose the register.
• Second read the level word.
• Third read the kit list.
• Fourth read the finish.
• Last read the bore if stated.

What to pick for your situation

Questions

Does a larger bore make a saxophone louder?

The catalogue does not state that. A listing may say 'large bore', but no maker page in this site's catalogue links a bore size to a loudness result. The site compares stated details and makes no sound claims.

Is a small bore better than a large bore?

Neither word is ranked on this site. Both are stated design details. The guides compare what a listing states, and they do not score one bore over the other.

Where is the bore located on the instrument?

In general terms, the bore is the inner tube of the saxophone's body, the column of air that runs from the neck to the bell. A listing may also mention the neck as a separate part.

Can I compare the bore of a soprano with the bore of a tenor?

No. Soprano, alto, tenor and baritone are different sizes, and each has its own bore as a design value. The word on one listing does not translate to another register.

Why does one listing mention bore and another does not?

Some sellers state the bore as a detail and others do not. A missing mention means the detail is not stated by the seller, nothing more.

Does the bore affect which mouthpiece I should choose?

The mouthpiece has its own specifications, such as chamber and facing. The bore is a separate part of the instrument. The catalogue does not state that one bore requires a particular mouthpiece.
