Programme notes and reflective report
Melodic Contour
 Whether it is a good combination of stepwise
and disjunct movements
 A good mixture of upward and downward
movements
 comprehensibility and spontaneity
Voice: range, characteristics,
form vs tessitura
 Whether the melody is suitable for singing
 Whether the rhythmic setting of the lyrics are
appropriate
 Whether different sections of a song highlight
different tessitura, so as to maximize the
effectiveness of the voice in terms of
dynamics/expression
Flute and Clarinet:
range, characteristics, articulation
 Whether the piece is idiomatically written for a
specific wind instrument
 Whether the piece utilizes the full pitch range
of the instrument, so as to explore the timbral,
dynamic varieties on different tessitura
 Whether the piece employs various kinds of
articulations/tonguing and effects
Violin and Cello:
range, characteristics, articulation
 Whether the piece is idiomatically written for a
specific string instrument
 Whether the piece employs articulation/
bowing markings (i.e. slurs), and performing
techniques (e.g., pizz.)
 As string instruments cover wide pitch
ranges, a piece shall avoid focusing only on a
narrow tessitura of the instrument
Counterpoint: setting a bass line
against a simple melody
 Whether the student is able to reduce the
melody into a skeleton of pitch movement
 It is a basic training of two-part one-to-one
counterpoint
 Whether the vertical intervals as well as the
horizontal intervals are satisfactory
Harmonizing a simple melody
 Whether the bass line works with the melodic
skeleton satisfactorily in one-to-one
counterpoint
 Whether the bass notes support the right
chord positions (i.e., different positions have
different meanings in functional harmony)
 Whether the choice of vertical sonority is
satisfactory
 Whether the voice-leadings from one chord to
the next are satisfactory
Piano Accompaniment:
melodic elements in chordal texture
 Whether the accompaniment is simply a
straightforward, square presentation of a
chord progression
 Whether the upper part or an inner part
provides some melodic interest
 Whether the accompaniment is also
appealing on its own
Musical Phrasing: cadence & barring
 Whether the materials are grouped in a two-
bar unit, four-bar phrase, eight-bar phrase, or
one with an unusual length
 Whether a phrase is marked by a cadence
and/or rhythmic devices
 Since bar lines are places where chord
changes, does the harmonic rhythm and
cadence reinforce the phrasing
Arranging a melody for piano
 A simple melody, especially a slow one,
played on the piano by the right hand alone is
not very idiomatic
 Whether the student can provide extra notes
to harmonize the melody
 Are there any textural varieties
 Are there extra parts to play against the
melody
 Is the melody presented in various octaves
with idiomatic figurations
Contrapuntal Writing for Two Parts
 Whether the two parts move independently
 Whether they combine to outline a harmonic
progression
 Whether they have individual characters
 Whether the rhythmic activities appear
spontaneously or in a square manner
 Whether the rhythmic unison they play at
some points provides a good textural variety
Arranging a simple melody
for violin and piano
 Whether the three parts (violin, piano right
hand & left hand) overlap with each other
 Whether one part carries the melody while
the other parts not interfering
 Whether the chord spacing is satisfactory
 Whether timbral differences are taken into
account
 Whether different roles are given to the two
instruments at different places
Percussion: timbral exploration
 Do we expect percussion to provide extra
chord notes, highlight the rhythmic writing,
reinforce the loud parts, supply a fuller
texture, or simply provide new sounds/timbre
 Does musical notation for percussion indicate
the sounds or the performing actions/manner
 Whether one uses the percussion
economically (i.e., not asking for many
instruments but having each playing one or a
few notes in the whole piece, etc.)
Drum Patterns in Rock Music
 Percussion as a textural provider
 How many layers are in the drum part
 Whether there is timbral variety within each
layer (i.e., snare - hand clap - rim shot; hi-hat
- tambourine, etc.)
 Whether the fill-in bar is interesting enough to
break the monotony of the repetitive bars
 Whether additional percussion is added in
selected places
Brass instruments:
range, characteristics, articulation
 Whether one contrasts trumpet-trombone
family with horn-tuba family
 Whether the written pitches are reasonably
not so high
 One may consider introducing the issue of
harmonic series in the discussion of pitch
production in brass
 Whether the music comes with precise
articulation markings (e.g., tonguing, etc.)
Chinese Plucked-String Instruments
 Sound envelope: fast attack and fast decay
 Various ways in producing sustained notes
(i.e., different types of tremolos)
 Whether the characteristic sounds of pitch
sliding are featured in the writing
Contemporary Techniques:
new modes, rational pitch organisation
 Does one use the standard scales (diatonic
or chromatic), modes (early music, nonWestern), or artificial scales
 Does one use twelve-tone serialism, x-tone
serialism, limited intervallic patterns, etc.
 Does one generate pitches according to
some systems of thought
 Does the rational pitch organisation make any
sense in aural effects
Contemporary Techniques:
creative harmonic experimentation
 Does one treat dissonance as important as
consonance
 Whether one defines further various degrees
of dissonance
 Does the new harmony focus on vertical
intervallic relationships
 Whether there are any special features in the
ways how an unusual chord is presented
Contemporary Techniques:
atonal & arrhythmic
 Whether there is any governing principle
behind the pitch organisation of atonal music
 Whether the composer aims to present free
atonality or well-organised pitch architecture
 Whether one looks for unpredictable rhythmic
writing or great rhythmic variety
 Whether the flexible rhythms help shaping the
music into comprehensible units or phrases
Extended Instrumentation Techniques
on Various Media
 Thoroughly explore the potentials and
characteristics of a the voice, acoustic or
electronic instruments
 Not avoiding the limitations, but featuring
noises as well as standard sounds
 Whether the unusual sounds are incorporated
into the piece in some meaningful ways; do
they appears just for the sake of having them
Large Scale Formal Structure
 A logical structure requires a good balance
between variety (changed) and coherence
(unchanged)
 Does the form features the contrast between
tension and relaxation
 Does one achieve this in careful control of
timing and proportion (e.g., whether the
climax is longer enough or appears at the
right moment, etc.)
Creative Sound Project
 As a composition of sounds rather than
pitches, one shall focus its creativity on the
rhythm, phrasing, dynamics, timbre, texture
and structure
 All kinds of sounds can be used, not limited to
the percussion, but sounds from any
everyday objects (newspapers, plastic bags,
food, etc.) or toys
 May use stories, poems, pictures as the
source of inspiration
Synthesizers and Electronic
Resources
 If one uses synthesizers, electronic
equipment, MIDI sequencing or computeraided sound synthesis, one shall feature the
unique aspects of these media (rather than
using them as a substitution of acoustic
instruments, for example)
 Unlike the reference recording for
compositions written for acoustic instruments/
voices, the recording quality for pieces written
for electronics weights highly
Programme Notes and
Reflective Report
 Besides explaining the use of music elements
and compositional devices in their
compositions, one may highlight specific
issues (e.g., formal structure, programmatic
association) which the examiner may
overlook
 One may also mention the limitations and
difficulties of the composition, and explain
why these things can’t be overcome (a good
way to show the candidate is fully aware of
the nature of music composition)
