Tutorial No.9. Assemble a ternary form melody, set the harmony, then generate an accompaniment
In this tutorials we shall utilize the fragment list from tutorial No 5,
but we shall only use the violin melody fragments, change this to a
clarinet, then write out the harmony, and generate a piano accompaniment in the
style of a Chopin waltz.
- Open the Musical Discovery Composing Board from the main MENU :-
Create -> Compositions -> Composing Board.
- Click the drop-down box labeled Fragment Lists at the top of the
screen, and select Tutorial 5 - Ternary Form. You should see 9 fragment icons
at the foot of the screen
- Assemble the top violin melody part onto the top row of the grid, by
dragging the icons for the violin fragments onto it. The ternary form for
this piece will be A A B A2, so drag the Theme A icon
twice, into the first and second squares. Then drag theme B, lastly
drag theme A2.
- Click the orange button Assemble
fragments, then hit the play button to listen to the melody
of this piece.
- In order to change the instrument to a clarinet, go to the main MENU
Create -> Compositions -> Bulk Changes to Tunes
- Under the bottom red heading Bulk Parameter Changes, check Change
Instrument and select clarinet
from the drop-down box below this. Hit the pink
button Perform Bulk Changes,
then click the play button to listen. You should hear the melody
played on a clarinet.
- Before you can generate an accompaniment, 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:-
Here are suggested chords for the 8 bars of theme A, which starts in A major
and modulates to E major. This theme is repeated, so the chords for bars 9-16
will need to be the same again.
