There are many different types of bagpipes, including several from the Celtic nations. Here's a brief description of some of the more common ones, particularly those from the British Isles.

The Bagpipe Society (UK) has a fantastic Bagpipe Guide containing further information about some of the more common bagpipes of Britain and beyond.

Scottish smallpipes (SSP)

Bellows-blown (though occasionally mouth-blown) pipes, with drones from a common stock and a parallel (straight/cylindrical) bore chanter. They are usually in the keys of A, D, C, Bb & sometimes G.

Pastoral / Union / Uilleann Pipes (UP)

Bellows-blown conical bore chanter extended with a foot joint, and able to over-blow giving almost two octaves. The three drones from a common stock are each pitched an octave apart, and there are none or more regulators (keyed drones). They are usually in the keys of D or C.

Northumbrian smallpipes (NSP)

Whilst technically these pipes are not Celtic (i.e. not from one of the Celtic nations), they are a close cousin to some of the varieties of Celtic pipes, so we include them here too.

“Bellows-blown smallpipes with a closed-ended parallel bore chanter. A common set consists of bellows, bag with four drones, tuned D, G, d, g, and a 7-keyed chanter. The drones may have tuning beads, commonly one on each drone, so that they can be retuned to E, A, e, a. Only 2 or 3 drones are used at a time, but this extends the range of possible keys from 2 (G and D) to 4 (D, E minor, G, A minor). The chanter has a range of almost 2 octaves (not chromatic) and it is possible to play a wide range of material on it. They are usually in the keys of F+ (20 cents sharper than F), F# & G. Most keys are available.

Lowland / Border pipes (BP)

Bellows-blown pipes, with drones from a common stock, and conical (or tapered) bore chanter. (Highland Reel Pipes and Northumbrian Half-long Pipes are essentially the same). They are usually in the keys of A, G or Bb.

Shuttle pipes (ShP)

Smallpipes, usually bellows-blown, with a double reed drone arrangement drilled into a single solid block, and each drone tuned with a slide. They are usually in the keys of A or Bb.

Lowland pipes

The term ‘Lowland Pipes’ refers to all Scottish bellows-blown and mouth-blown pipes with drones from a common stock, including BP, SSP and Pastoral Pipes, but excluding Highland Reel Pipes. (Sometimes LP are defined as only those pipes with a conical bore chanter and drones from a common stock, i.e. BP).

Cauld wind pipes

This is a general term sometimes used for Scottish bellows-blown (‘cold’ wind) pipes.
