Tutorial No.7.
Mix and match assorted Mozart fragments to create a new
melody, with an accompaniment..
We hope Wolfgang won't turn in his grave, because we are about to pick four
fragments of 4 bars each, from diverse works by him, and put them together in a
way he never intended!
Our fragments will be extracted from the trio from Symphony no 39 in Eb
K543, the slow movement of his clarinet quintet K581, the menuetto
from his Divertimento in D, and the menuetto from his trio in Eb K252. All of
these are in the same time signature, namely 3/4, as this is vital for Musical
Discovery to be able to join them together. We shall choose D major as our
key, so we shall need to transpose the two works which are in Eb.
- Starting from the main MENU, select File -> Load Musical
Discovery File
- Click the down arrow to open up the drop-down list, and search and select Quintet
in A K581 for clarinet and strings - 2nd movt. by Mozart.
- From the MENU, select Create -> Compositions -> Bulk changes to
tunes, and extract fragments. Pres the Play button to listen to
this tune.
- In the Select a single track drop-down box, choose 1-
Clarinet. Set the from-bar to 1,
and the to-bar to 4.
- Click the lilac button Replace current tune with specified bar range and
tracks. This extracts just bars 1 - 4 into the current tune in memory.
- Click the purple button
- Add
entire current tune as a new fragment on the composing board.
Now click the green
OK button on the Store fragment as dialog box, without changing its
name.
- Repeat steps 2 - 6, but selecting Divertimento no
2 in D - menuetto - by Mozart, select track
2 violin-2,, bars from 5 to 8.
- Repeat steps 2 - 6, but selecting Trio in Eb K252
2nd Movt. menuetto by Mozart. Select track
2 - violin, and bars from 1 to 4.
As this fragment is in Eb we need to transpose it down one
semitone to D major. Whilst still in the Bulk changes to tunes, and
extract fragments screen, go down to the transpose section, set Number
of Semitones to 1, and transpose direction to down. Click the green
button perform transpose.
Then Click the purple button
- Add
entire current tune as a new fragment on the composing board.
Now click the green
OK button on the Store fragment as dialog box, without changing its
name.
- Repeat steps 2 - 6, but selecting Symphony
no 39 in Eb K543, 3rd Movt. trio by Mozart. Select track
4 - First Clarinet, bars from 5
to 8. This also need to be transposed
down one semitone from Eb to D major, as described in step 8 above..
- Click the orange button Assemble
fragments on the board into a new tune. Listen by clicking
the Play button. The 4 parts go together fairly well, but the tempo is too
slow, and the instrument switches from clarinet to violin.
- From the main MENU select Edit -> Expression (Tempo and
dynamics) to bring up the expression screen. Draw a red line at the
start of the tempo panel, at about 130 crotchets per minute. Then go
to the main MENU, Edit -> Track data and change the track
description to Mozart did this! and click on the Inst
No and select strings from the
drop-down box. Then click on the button Change instruments to default for
entire track. Now listen to your new arrangement by clicking the play
button.
- As an extra option, you might like to add an accompaniment using the
Alberti bass which Mozart used frequently. You need to write in the chords,
so go to the main MENU Create -> Accompaniments. If you are
confident about harmony and cadences, fill in the chord names as you see
fit. If you want a suggestion, try the following sequence:-
Bar 1 |

Click the green button Select
Accompaniment Pattern at top left of the screen. In the drop-down box
labeled Upper Accompaniment Instrument, at left of screen, select strings.
Then click on the Alberti Bass (Mozart) button in the first column of
patterns. Let's hope you're impressed and Mozart's not too distressed!
