infoWhy this? The blues demonstrates how musical conventions are shaped by social and historical context and how harmony, structure, rhythm, and expressive pitch choices create a recognisable style. Performing the 12-bar blues and improvising with the blues scale develop keyboard coordination, stylistic awareness, and confidence in creating and varying motifs.

scheduleWhy now? At the start of Year 8, this unit extends earlier work on triads, basslines, two-handed keyboard playing, and constrained improvisation. The repeating 12-bar structure provides a secure framework for experimentation, establishing harmonic and compositional foundations for later rhythm and arrangement units.

The elements of music used in this unit are Dynamics, Rhythm, Structure, Melody, Instrumentation, Tempo, Timbre, Texture, and Harmony (often taught as DR SMITH vocabulary).
In any major key, the primary blues chords are the I, IV, and V triads, built on the 1st, 4th, and 5th degrees of the scale; in C major these are C, F, and G.
A triad is a chord made of three notes: the root, the third (major or minor), and the fifth, typically played in root position as root–third–fifth.
The 12‑bar blues is a repeating 12‑measure structure using I, IV, and V chords; a common pattern in C is C–C–C–C, F–F–C–C, G–F–C–C (each letter indicates one bar).
A walking bassline is a steady crotchet bass part that outlines the chord changes using stepwise movement and arpeggios, often ascending and descending smoothly.
The C blues scale consists of the notes C, Eb, F, Gb, G, and Bb (returning to C at the octave).
In the key of C, the lowered (flat) 7th is Bb, whereas the natural 7th is B.
Chromatic notes such as Bb (flat 7) and Eb (flat 3) add a 'bluesy' colour by lowering scale degrees to create expressive tension against the major harmony.
Pulse is the regular beat of the music, while rhythm is the pattern of note durations organised over that pulse.
Tempo markings indicate speed: Largo means very slow, Andante means at a walking pace, and Allegro means fast.
Articulation describes how notes are performed (for example, accented, legato, or staccato) and affects clarity, fluency, and style.
Accenting the first beat of each bar in a walking bass helps define the metre and strengthens the groove in blues performance.
Timbre (tone colour) is the characteristic sound quality of an instrument or voice, while texture describes how musical layers combine (for example, monophonic or homophonic).
Harmony describes how chords are built and progress; blues harmony commonly features dominant 7th sonorities on I, IV, and V.
On a keyboard, a flat lowers a note by one semitone; Bb and Eb are the black keys immediately to the left of B and E, respectively, but not all flattened notes are black keys because Cb and Fb are white keys.
Robert Johnson was a Delta blues musician who recorded "I Believe I'll Dust My Broom" in 1936, and his style strongly influenced later blues and rock musicians.
In a typical blues ensemble or keyboard setup, the left hand or bass part provides the bassline or chords while the right hand plays melody or improvised lines.
A motif is a short, memorable musical idea that can be repeated and varied to shape an improvisation or composition.

Build I, IV, and V triads in C major on the keyboard, placing the thumb on the root and stacking notes as root–third–fifth with clean, simultaneous attacks.
Perform the 12‑bar blues chord progression fluently at a consistent tempo, changing chords exactly at the bar lines and completing full 12‑bar cycles without hesitation.
Play a left‑hand walking bassline in crotchets that ascends and descends to outline the I, IV, and V chords in C, with a clear accent on beat 1 of each bar.
Locate and play Bb and Eb on the keyboard accurately and incorporate them as chromatic tones in the bassline using an efficient left‑hand finger pattern.
Improvise a right‑hand melody over the 12‑bar blues using the C blues scale, including rests and a mix of long and short note values to create rhythmic variety.
Devise a short motif and develop it through repetition, rhythmic alteration, and small pitch changes while staying within the C blues scale and the 12‑bar structure.
Apply articulation deliberately (for example, accents on beat 1 and smooth legato lines) to enhance fluency and stylistic authenticity in blues performance.
Maintain a steady pulse and coordinate ensemble entries and endings, counting 12‑bar cycles so all parts change chords together.
Evaluate a performance using DR SMITH vocabulary, giving one precise strength and one target linked to timing, accuracy, articulation, or stylistic character.
Compare two blues recordings (including Robert Johnson) by identifying structure, instrumentation, tempo, and use of the blues scale, justifying points with specific musical evidence.
