Lesson 57: Major Work Study, Part 1 — Overview and First Movement

Begin a four-lesson study of Loeillet of Ghent's Sonata in D minor, Op. 1 No. 1 — the work the next four lessons all return to.
Take the opening Largo from sight-read to a confident, expressive performance.
Hear and name the affect of the Largo against the three movements that follow.

Lesson 53 — complete short Baroque sonata (architectural awareness).
Lesson 48 — Baroque ornamentation practice.
Lesson 54 — flattement (for the Largo's cadences).

Multi-lesson work study.
Affect across movements.
French Baroque slow-movement style.

One piece, four lessons. Not because it is hard. Because it is worth knowing well.

The next four lessons are an extended study of a single work: Jean-Baptiste Loeillet of Ghent's Sonata in D minor, Op. 1 No. 1. Lessons 51, 52, and 53 have already trained the procedures — chunked practice, theme-and-variations thinking, multi-movement planning. This sequence applies those procedures, in detail, to one piece. Lesson 57 introduces the work and learns the first movement; Lessons 58 and 59 take the slow and fast inner movements; Lesson 60 brings the whole sonata to performance.

The reason for the depth: a learner who has played one sonata thoroughly knows more about Baroque style than a learner who has skimmed twelve. The piece becomes a reference — everything you hear afterward is heard against it.

The whole sonata at a glance

Four movements, slow-fast-slow-fast — the standard sonata da chiesa plan. Each has a defined affect; the contrasts are the architecture.

I. Largo: Noble, French. The opening descent is a sigh, not a gesture. Quarter = 50.
II. Allegro: Italian energy. Running eighths, sequence figures, brilliant. Quarter = 110.
III. Adagio: Heavier than the Largo. The harmonic weight sits on the second beat. Quarter = 55.
IV. Giga: Compound dance. Light. Lifted. Dotted quarter = 65.

Movement I — Largo

Read through the opening Largo at half tempo, once. Stop. Do not fix anything; just listen for the shape. The first phrase is two bars long — a descent from D, leaning on the eighth notes E-F, resolving down to D. The second phrase climbs back up and lands on the dominant. The architecture of the whole movement is built out of those two gestures, alternating.

Practice plan — the Largo only

For this lesson, you are not learning the whole sonata. You are learning the Largo and listening to the other three. Four sessions over the next week:

Session 1 — read all four movements once at half tempo: Then put the score down and try to sing through the four opening motives from memory. The architecture has to be in the ear before the fingers can serve it.
Session 2 — the Largo, hardest-bar work: The cadence figures in bars 4–5 and at the end of the movement are the tricky parts. Apply the Lesson 51 chunked procedure to them.
Session 3 — the Largo, chunks: Play the first half (to the first cadence) as one chunk; the second half as another. Stop when each chunk plays the same way twice in a row.
Session 4 — the Largo, end-to-end: Two run-throughs at quarter = 50, recording the second. Listen back without the score and mark the bars you would work on next.

One ornament — flattement on the cadence

The Largo's two cadences (mid-movement and final) are the textbook flattement context from Lesson 54. Apply the finger flattement only on those two cadential notes — not on every long note. Less is more in this style.

Now play these

Loeillet of Ghent: Sonata in D minor, Op. 1 No. 1: The piece of the next four lessons. Read all four movements; learn the Largo in detail.
Loeillet of Ghent: Sonata in F major, Op. 3 No. 3: A companion piece. Compare its slow movement to the Largo above; the French style is consistent across the Op. 1 and Op. 3 sets.

When the opening Largo is in your hands at quarter = 50, with flattement on its two cadences, and you can sing the opening motive of each of the other three movements from memory, move on to Lesson 58.
