Humdrum lab 4

This lab introduces the digital scores of the Josquin Research Project

Download the data

First download the data by genre:

    cd ~/Desktop
    mkdir jrp
    cd jrp
    mkdir masses
    (cd masses; humsplit h://jrp/Zma)
    mkdir motets
    (cd motets; humsplit h://jrp/Zmo)
    mkdir songs
    (cd songs; humsplit h://jrp/Zso)

There are three basic genres: secular songs, religious songs (motets), and music for the mass ordinary.

You can also download works by composer, such as Jean Mouton:

    humsplit h://jrp/Mou

Ockeghem:

    humsplit h://jrp/Ock

Josquin securely attributed works:

   humsplit h://jrp/Joa

Josquin not securely attributed works:

   humsplit h://jrp/Job

All of Josquin works:

   humsplit h://jrp/Jos

Alternatively, the JRP database is available on github at https://github.com/josquin-research-project/jrp-scores

How much data is there?

How many files:

    cd ~/Desktop/jrp
    ls masses motets songs | grep krn | wc -l

(Github is more recent).

How many notes:

    cat */*.krn | extractx -i **kern | census -k

There are 803,046 notes

By genre:

   for i in masses motets songs
   do 
      echo "$i:"
      cat $i/*.krn | extractx -i **kern | census -k | grep "Number of notes"
   done

Final tone

 $ finalis songs/*.krn | sortcount
58	G 
36	D
27	A
13	F
10	C
7 	E
1	B-

One song with a final on B-flat.

Scale degrees

The music is not in major/minor modes as modern tonal music is conceived, so there is no key designations in the files. There is a script in Humdrum Extras which will add a key designation based on the final tone of the music so that scale degree information can be extracted from the scores:

$ finalis-tonic songs/Jos2724-Madame_helas.krn | less

Calculate scale degrees patterns of length 5 in the B-flat song:

$ finalis-tonic songs/Jos2724-Madame_helas.krn | deg -at | serialize | context -n 5 | ridx -H | sortcount
6	5 4 3 2 1
4	1 7 6 5 6
4	2 3 r 2 3
4	4 3 2 1 4
3	1 7 6 7 1
3	6 5 4 3 4
3	6 5 6 5 1
3	1 7 1 7 1
3	7 6 5 6 5
3	6 2 1 7 6

Calculate scale degrees for all songs:

$ finalis-tonic songs/Jos2724-Madame_helas.krn | deg -at | serialize \
         | grep -v = | context -n 5 | ridx -H | sortcount | head -n 10
6	5 4 3 2 1 
4	2 3 r 2 3
4	1 7 6 5 6
4	4 3 2 1 4
3	4 3 2 1 2
3	6 5 4 3 2
3	2 1 7 6 5
3	1 7 1 7 1
3	3 4 3 2 1
3	5 6 5 4 3

Length-5 scale degree patterns in songs:

$  finalis-tonic songs/* | extractx -i **kern | deg -at | serialize -L \
          | egrep -v '=|r' | context -n 5 | ridx -H | sortcount | head -n 10
427	5 4 3- 2 1
302	3- 2 1 7- 1
297	4 3- 2 1 7-
236	2 1 7- 6 5
219	2 3- 2 1 7-
219	1 2 3- 4 5
198	7- 6 5 4 5
196	1 2 3- 2 1
193	7- 1 2 3- 2
185	1 7- 6 5 4

Exercise: How do the most common scale-degree patterns compare to masses and motets?

Keyscape

The B-flat song has an interesting harmonic structure:
