This lab is about the wikifonia data.
Basic information
How many files
ls *.krn | wc -l 6710
How many have lyrics:
grep -l "\*\*text" *.krn | wc -l
5460
How many have chords:
grep -l "\*\*text" *.krn | wc -l
6282
How many have two or more verses:
grep -l "\*\*text.*\*\*text" *.krn | wc -l
2006
Duration
What is the duration of all songs if played back-to-back and at the specified tempo without repeats?
gettime -T *.krn | tail -n 1 286:50:23.1354 hours
What are the longest songs:
gettime --simple -T *.krn | sort -k2 -nr | head -n 10
WF6618.krn: 3120
WF0181.krn: 3120
WF0182.krn: 1864
WF3616.krn: 1420
WF6336.krn: 1134
WF5131.krn: 909
WF6068.krn: 785
WF5004.krn: 696
WF3226.krn: 671
WF1249.krn: 664
The -k2 option means to sort by the second column of data. -n means to sort numerically rather than alphabetically, and -r means to sort by highest first.
What are the shortest songs:
gettime --simple -T *.krn | sort -k2 -nr | tail -n 10
WF2814.krn: 16
WF2806.krn: 16
WF2795.krn: 16
WF2785.krn: 16
WF2856.krn: 14
WF2852.krn: 12
WF2799.krn: 12
WF6338.krn: 8
WF5609.krn: 8
The shortest song in VHV:
cat WF5609.krn | pbcopy

-U means extract the duration unit from the meter (the bottom number).
-a means to append the analysis to the end of the lines (keeping the original input score).
Chord labels
How many unique chord labels are there?
extractx -i mxhm * | ridx -H | sortcount | wc -l 1399
What are the most common ones:
extractx -i mxhm * | ridx -H | sortcount -p | head -n 10 7.21 C major 6.14 F major 4.94 G major 4.83 G dominant 4.07 C dominant 3.55 D dominant 3.28 B- major 2.81 E- major 2.3 D major 2.25 F dominant
