Eduqas GCSE Music: Musical Forms and Devices (Area of Study 1) - forms, devices, the periods and the Bach Badinerie

What this area covers

This area is Area of Study 1, Musical Forms and Devices, which covers how Western Classical music (roughly 1650 to 1910) is structured and how its material is treated. It is tested in the Component 3 appraising exam, with two questions, normally including one on the set work, the Bach Badinerie. The area covers the structural forms, melody and harmony and tonality, rhythm and metre and tempo, the three style periods, and the set work in depth.

This guide ties together the six dot-point pages for the area.

The structural forms

The main forms are binary (AB, two repeated halves, no full return of A), ternary (ABA, with a return of A after a contrast), rondo (a recurring refrain with episodes, ABACA), theme and variations (a theme stated then varied), minuet and trio (a ternary triple-time dance) and the song forms strophic (same music per verse) and through-composed (new music throughout). The deciding question is whether and how the opening material returns.

Melody, harmony and tonality

Melody can be conjunct (stepwise) or disjunct (leaping), and uses devices such as sequence and ornamentation (trills, mordents, appoggiaturas). Harmony is built from chords and cadences: perfect (V to I), imperfect (to V), plagal (IV to I) and interrupted (V to VI), with the pedal (a held note) a common device. Tonality is major or minor, with modulation (a change of key, often to the dominant or relative major or minor).

Rhythm, metre and tempo

Note values halve as you go down (a semibreve equals four crotchets), and a bar must add up to its time signature. Simple time divides each beat into two ($\frac{3}{4}$, $\frac{4}{4}$); compound time divides it into three ($\frac{6}{8}$). Tempo terms run from Largo and Adagio (slow) to Allegro and Presto (fast). Rhythmic devices include syncopation (off-beat accents), dotted rhythms (long-short), the tie and triplets.

The Western Classical Tradition periods

The Baroque (Bach, Handel, Vivaldi) has a continuo, terraced dynamics, ornamentation and small forces; the Classical (Haydn, Mozart) has balance, clarity, a Classical orchestra and graded dynamics; the Romantic (Schubert, Brahms, Tchaikovsky) has a large orchestra, chromatic harmony, expressive melody and programme music. Placing an extract is a matter of matching what you hear to these fingerprints.

The Bach Badinerie set work

The Badinerie is the fast final movement of Bach's Orchestral Suite No. 2 in B minor, for solo flute, strings and continuo. It is a Baroque dance in binary form, in B minor, in fast duple time, with brilliant, agile semiquaver flute writing using sequence and a wide range. Know its form, key, flute writing and texture in detail, and confirm the current set work with your centre.

How to revise this area

1. Read structure as returns. Decide the form from whether the opening material comes back, and how often.
2. Learn the cadences and tonality. Drill the four cadences by sound and the major/minor and modulation vocabulary.
3. Read rhythm and metre. Count beats, test how each divides, and name the time signature and any rhythmic devices.
4. Fix the period fingerprints. Learn the Baroque, Classical and Romantic signals so you can place any extract.
5. Master the set work. Know the Bach Badinerie by ear and on the score, in real detail, and confirm it with your centre.
