A Beginner's Guide to Baroque Ornamentation

What an Ornament Is Really Doing

Ask a newcomer what ornaments are for and you will often hear something about decoration: frills added to a melody to make it prettier. That is not quite right, and the misunderstanding makes Baroque music harder to enjoy than it needs to be. An ornament is a way of pressing on a note, delaying a resolution, or making a cadence sound like an arrival rather than a full stop. It is rhetoric, not glitter.

Baroque composers expected performers to shape a line with these small figures, and many left them unwritten, trusting the player to know where they belonged. In chamber music this matters enormously, because with one player to a part there is nowhere to hide. The ornament is exposed, intimate, and part of the musical argument. Once you can hear what each type is doing, the music stops sounding busy and starts sounding eloquent.

Trills: The Cadential Signpost

A trill alternates the written note with the note above it. In Baroque practice it usually begins on the upper note, so a trill on D starts E–D–E–D. It also usually ends with a short turn down to the note below and back, known as a termination, which signals the harmony's arrival instead of simply stopping.

• Trills are not all the same speed or length. A brisk one in a fast movement can flash past in a moment; a slow one in a lament can last most of a bar.
• They cluster at cadences. Listen for the point where a phrase leans towards its resting note, and you will almost always find a trill there.
• They belong to the harmony. A trill over a dominant chord sounds tense; the same trill over the tonic sounds settled.

Try this: follow the upper line of a slow movement and simply notice when it starts to shake. That shake is the music telling you the phrase is about to close, even before the bass confirms it.

Mordents: Quick, Rhythmic, on the Beat

A mordent is a rapid three-note flick: main note, neighbour, main note. It is rhythmic rather than decorative — it sits on the beat and takes its time from the note it decorates, so the following note is not delayed. A common beginner's error is to play mordents so casually that the beat wobbles. Good players make them crisp and metrical.

A word on names: in British usage, a mordent goes to the note above and an inverted mordent goes to the note below. In much American and continental usage the terms are reversed. If you read a programme note or an edition that seems to contradict what you have learned, this is almost certainly why — and it is nothing to worry about. What matters is that you can hear whether the flick leans upwards or downwards.

Appoggiaturas: The Expressive Sigh

The appoggiatura is the most expressive of the common ornaments, and the easiest to love. It is a foreign note placed on the beat, taking its time from the note that follows — often half the value, sometimes two-thirds in dotted rhythms — and then resolving by step. Because it is usually dissonant against the bass, it creates a small moment of tension that the main note releases.

In slow movements, appoggiaturas are frequently unwritten. A violinist or oboist may add one where the harmony invites it, and a harpsichordist realising the continuo may add one at the same moment. This is why two performances of the same trio sonata can sound so different: the sighs are in different places. When you hear a phrase that seems to ache slightly before it settles, you are probably hearing an appoggiatura, whether or not it appears in the score.

How to Listen Without Getting Lost

You do not need to name every ornament. You need to hear what it does to the shape of the line. A few practical habits help.

• Follow one part at a time. Take the top line on a first hearing, then the bass on a second. Ornaments become far clearer when you are not trying to track four things at once.
• Mark the cadences. Most ornaments gather at the approach to a cadence, like signposts before a junction.
• Listen to repeats. In binary dance movements and da capo arias, the repeat is where performers ornament most freely. The second time through should not sound identical to the first.
• Compare two recordings of the same movement. The differences will teach you more in ten minutes than any textbook.

Above all, remember that ornaments exist to clarify the line, not to obscure it. If a performance sounds cluttered, the ornaments are probably being applied too thickly or too uniformly — a fault of taste, not of technique.

A Short Route In

Start with Corelli's trio sonatas and the Op. 5 violin sonatas, where the ornamented slow movements are a masterclass in restraint. Move on to Handel's Op. 2 trio sonatas, full of expressive appoggiaturas, and to Bach: the slow movement of the Fifth Brandenburg Concerto, where the harpsichord's line is ornamented at length, and the sonatas for violin and harpsichord. Telemann repays patience, and if you want French colour, Couperin's chamber works and Rameau's keyboard pieces arranged for small ensemble are revelatory. Purcell's viol fantasias have fewer ornaments but show how much expression can live in a single decorated phrase.

Live performance is where this really clicks. A lunchtime recital in a parish church, a university concert series, or your local chamber music society will put you within a few feet of the players, and at that distance every trill and mordent is audible as an act of choice. Go twice to the same programme if you can. The second time, you will hear the ornaments not as extras but as the music itself, thinking aloud.
