ACTIVITY 10:
ACCIDENTAL NOTES AND TRANSPOSITION
- Indicate which is the highest and lowest of each pair of notes, having listened to it note by note. You will find the intervals in the file INTERVAL.

Using the program "Music": to listen note by note press F5.
|
Say which of those intervals are ascendent (low to high) and which are descendent (high to low).
Indicate the size (2nd, 3rd, 4th etc.) of each interval.
- Compose a melody of 8 bars in 2/4 time with whatever notes you choose, with a maximum interval of a third between one note and the next.
- Make up another melody also in 2/4, this time limiting the intervals to a fifth.
- After listening to your two melodies what difference can you find between them?
- Retrieve the file ENCIAM2. Write a second voice as an accompaniment at an interval of a third.

Una plata d'enciam (Catalonia)
- Do the same with the following files: DOSYDOS, GAYGORDO, OHCHEBEL, PENTOZAL and SLAAP:
Dos y dos son cuatro (Spain)
The Gay Gordons (United Kingdom)
Oh che bel castelo (Italy)
Pentozalis dance (Greece)

- Retrieve the melody FREREJAC from 10ALTERA and raise the pitch of all the notes by a 2nd. What happens?
Does it sound alright?
Frère Jacques
Place a sharp sign (#) where you think it should go to make the tune sound alright, and check that the difference of tones between the original melody and your own is of one tone.
|
|
|
Using the program "Music": sharp sign # key S.
|
Starting with the original melody again lower all the notes by a 2nd interval and then place a flat sign (b) where you think necessary. Check to see that the tone difference between the original melody and your own is of one tone.

Músic : flat b key B
|
Deactivate the bar line option. Write the scale of C and force a bar ending, which we will use as a visual separator Then write the scale beginning with G (interval of a 5th) and listen to them. Add sharps where necessary to make it sound the same as the scale of C only higher. To listen to just one scale place the cursor at the beginning of the scale so that it plays from that point onwards.
|
|
|
Using the program "Music": To deactivate the bar lines press 0 (zero). To force a bar ending press F. To listen to just one scale at a time place the cursor at the beginning and press F4.
|
Force another bar ending and begin the scale with F. Add a flat so that it sounds the same as the others (in relation to the size of intervals). Repeat the exercise with D, adding sharps.
|
|
|
Using the program "Music": to force the bar ending press F again.
|
- Retrieve the piece 9SIMFBET and having listened to it, change the key signature to C minor and see what has happened to the notes. What interval has the melody risen or fallen by and how many alterations are there?
|
|
|
Using the program "Music": change the key signature with key A.
|
- Load the piece PATUM from 10ALTERA. Listen to it. Put it in the key of F and listen again.
|
|
|
Using the program "Music": change key with K.
|
Do the same with the following pieces in 10ALTERA: MINUET2 and BELLSULL.
- Search amongst the files for three songs written in the key of F (usually in voice 3, the accompaniment). Listen to these third voices silencing the other two.
|
|
|
Using the program "Music": silence the voices by selecting MUT voice.
|
- Retrieve the piece CANTPLUJ from 10ALTERA. Look at it on the screen; listen to it on its own, then change to the key of G. What changes do you see?
