All Students preparing for Grade exams are
recommended to use the Hofnotes on-line
training pages to practise for the aural tests.
At
higher grades you must be able to discuss with the examiner musical
features such as texture,
form,
style, and
period of a piece of music.
My own web pages to help with these parts of the test at Grade 5+ and at
GCSE
are available
here!

Elements of musical form
The elements of a musical work are:
- themes: its
musical motifs and melodies
- tonality
or key
-
rhythm, time signature and tempo
- development:
how these themes are varied and extended throughout
- repetition:
how some sections or ideas recur in order to frame and punctuate the work
- proportion:
the relative space given to certain ideas or sections of the work
A musical idea or extended melodic motif. A theme has a structure in itself, as well as tonality and rhythm.
It is built out of:
sentences...
and within them...
phrases....
and within those...
sections or strains...
and smaller even than these...
motives
Think of a piece you know well. Can you break it
into sentences, phrases, strains and motives?
How small an
element is the motif?
Play the
piece: you may notice other phrases especially in the left hand
part. Notice
how playing a piece through adds to the experience of analysing the printed
page or aural memory.
Look at the score of a piece you know well. Can you
identify blocks of music in different keys? Can you identify the point at
which the key changes? Does it happen all at once, or is it more of a
gradual process?
Play the piece, and listen as you play for how the key change - or
modulation - sounds. Try to find examples in pieces you know of the
following very common key changes:
-
into relative minor (a mood shift - more reflective, more sad, more ominous)
-
into tonic minor (a shift to a more contemplative mood; a momentary 'wrong note'
sensation if the original theme is repeated with the flattened third)
-
into dominant major (a feeling of new confidence and 'lift', from the sharpened
fourth in the original key turning into the leading note of the new key)
- up
a tone (a very obvious stepwise move, almost 'cheesily' common in musicals and popular songs)
The classical symphony uses tempo and metre to delineate different movements.
Here the previously heard themes and ideas
are treated in new ways, often modulating through different keys, so that they
sound new. As symphonies and the orchestras performing them became larger,
the development became longer, more complex and more adventurous, with Beethoven
so far departing from convention as to introduce new themes in this section in
his Eroica Symphony.
See Sonata form pages
Especially in Classical music, the different structural parts of a musical work often vary in length
according to a fairly strict pattern.
In
this Ecossaise by Hummel, the first section is 16 bars long (8 bars repeated).
The second section, starting at 00:13, balances this exactly, ending at 00:26.
The third section has no new material, and instead repeats material from the
first two sections with out their internal repeats so ends at 00:39.
In
the Trio to Beethoven's Sonata in C# minor Opus 27 No 2 ('Moonlight'),
the first section runs for around half the time as the second part.
