Table 5 A. — The compass of the songs is shown in this table. 

 The present analysis differs from that of Table 2A in that it 

 concerns the entire range of the song, while Table 2A indicated 

 the interval between the keynote and the first note. There is 

 accordingly a difference in percentages. For instance, 25 per cent 

 of the songs have a compass of 12 tones, but only 2.3 per cent 

 begin on the twelfth above the keynote. In this, as in Table 2A, 

 the largest percentages are on eight and twelve. It is noted in 

 Table 5A, though not shown on the diagram, that three songs have a

compass of 17 tones, or two octaves and two tones. The singers of 

 these songs were men with falsetto voices. (See fig. 6.) 



TaMe 6 A. — Tlie percentages shown in this table are not the same 

 as those shown in figure 7, though both are concerned watli the tone 

 material of the songs. The table indicates the character of the tone 

 material by referring it to a keynote, while the diagram indicates the 

 amount of the tone material, or the number of scale degrees in the 

 song. Attention is directed to four groups in the table: The second 

 five-toned scale (minor pentatonic), comprising 12 per cent; the

fourth five-toned scale (major pentatonic), comprising 23 per cent; 

 the group containing only the tones of the major or minor triad, 

 comprising sHghtly more than 1 per cent; and the group comprising 

 all the tones of the diatonic octave, 6 per cent. In compihng the 

 data shown in figure 7 a degree of the scale occm"ring in two octaves 

 is, of course, counted only once. It is thus seen that 49 per cent of 

 these songs contain only 5 scale-degrees, 23 per cent contain 4 scale- 

 degrees, and 20 per cent, 6 scale-degrees, while 6 and 2 per cent con- 

 tain, respectively, 7 and 3 degrees of the scale.
