Reading and analysing scores: clefs, key and time signatures, transposing instruments, score layout, identifying chords and cadences from notation, and applying the musical elements to a printed extract.

What this dot point is asking

Score-reading and analysis are the skills that let you answer the Section A questions that use a printed score in Component 1. AQA wants you to read clefs, key and time signatures, understand score layout and transposing instruments, identify chords and cadences from notation, and apply all the musical elements to a printed extract quickly and accurately under timed conditions.

Reading the basics

A full orchestral score is laid out in a fixed order from top to bottom: woodwind, then brass, then percussion, then any keyboard or harp, then the strings (violins, violas, cellos and double basses) at the bottom. Knowing this order means you can find an instrument quickly without reading every stave. The alto clef centres middle C on the middle line and is read by the viola; the tenor clef centres middle C on the second line from the top and appears in high cello, bassoon and trombone parts to avoid excessive ledger lines. To decide major or minor from a key signature, do not assume the relative major automatically: check the final bass note and look for an accidental that raises the leading note, which signals the minor.

Transposing instruments

The reliable method is to think in intervals. A clarinet in B flat sounds a major second (a tone) below the written note, so a written D sounds concert C. A horn in F sounds a perfect fifth below, so a written G sounds concert C. A trumpet in B flat also sounds a tone lower. The cor anglais (in F) sounds a fifth lower, and the double bass and the guitar sound an octave lower than written. When you are asked for the harmony of a passage, always convert any transposing parts to concert pitch first, or you will name the wrong chord.

Identifying chords and cadences from notation

To name a chord, write out the sounding pitches (after transposing), stack them into thirds to find the root, then label it (for example I, IV, V or by chord name) and check for inversions from the bass note: root in the bass is root position, the third in the bass is first inversion, the fifth in the bass is second inversion. Cadences appear at phrase ends: look for $V$ to $I$ (perfect), a phrase ending on $V$ (imperfect), $IV$ to $I$ (plagal) or $V$ to $vi$ (interrupted). The bass line is your fastest route to the cadence: a falling fifth or rising fourth in the bass into the tonic almost always signals a perfect cadence.

Analysing the whole extract

Work systematically through the elements rather than describing impressions: melody and motif, harmony and tonality, rhythm and metre, texture, structure, and instrumentation, citing bar numbers as evidence for every claim. A good exam routine is to annotate the score in the reading time, marking the key, the cadences, the texture changes and any modulation, so that when the question comes you can quote bars instantly. Bar references and precise terms are what earn marks; an unlocated general comment earns little.
