but in songs with the octave complete or nearly complete, the 

 percentage is almost identical. A slightly larger percentage of the 

 Chippewa songs contain no accidentals, and the number of purely 

 m(4odic songs differs by only 1 per cent in the two groups. The 

 difference in songs beginning with a downward progression is also 

 only 1 per cent, and the proportion of ascending and descending 

 progressions differs by 2 per cent. Differences of 1 to 6 per cent 

 mark the frequency of occurrence of various intervals of progression. 

 The average interval in the Sioux songs is slightly smaller than in the 

 Chippewa. 



In key the Chippewa songs show a preference for F, F sharp, 

 and G. A slightly larger proportion of the Chippewa songs begin 

 on the accented part of the measure, and a smaller percentage 

 begin in 2-4 time. The percentage of Sioux songs having a change 

 of measure-lengths is considerably larger than that of the Chippewa. 

 In the rhythm of the drum there is a difference, the Chippewa having 

 a much larger percentage with the accented drumbeat preceded by a 

 short, unaccented beat. The proportion of songs containing rhythmic 

 units is 64 per cent in the Chippewa and 68 per cent in the Sioux. The 

 metric unit of the voice shows greater variety among the Chippewa 

 but the drum shows the greater variety among the Sioux. The 

 metric unit of voice and drum shows much greater divergence among 

 the Chippewa, only 36 per cent having the same metric unit, wliile 

 among the Sioux the corresponding proportion is 62. 



Referring to the table of rhythmic units (19A), we note that the 

 percentage of Sioux songs which contain a rhythmic unit is larger than 

 that of the Chippewa. 



Of the Sioux songs 169 contain one or more rhythmic units, these 

 units, or phrases, being transcribed on pages 528 et seq. in groups simi- 

 lar to those which appear in the text of the work. Examining these 

 units, we find no duphcations except the following phrase, ^.fl,., 

 which occurs in 11 songs (Nos. 35, 36, 58, 115, 164, 194, 195, 225, 226, 

 229, 230) . We note also that an accented sixteenth note followed by a 

 dotted eighth note, which characterizes this plirase, is the first count- 

 division in the rhythmic units of 26 songs (Nos. 7, 26, 33, 41, 113, 116, 

 119, 131, 134, 155, 156, 160, 166, 167, 170, 171, 186, 188, 199, 202, 220, 221, 

 222, 231, 235, 238) . Thus it is seen that this count-division character- 

 izes the rhythmic units of more than 16 percent of tlie Sioux songs under 

 analysis. Turning to the rhythmic units of the Chippewa songs (BuU. 

 53, pp. 309-333), it is found that this count-division is present at the 

 opening of slightly less than 3 per cent of the entire number (Nos. 

 110, Bull. 45, and Nos. 64, 90, 92, 116, 131, 153, 163, 174, Bull. 53). 

 In the summary of analyses in Bulletin 53 (p. 11) it is stated that — 



There is ... a di^^.sion of a count C 1*1 which occurs in Chippewa songs recorded on a 

 reservation showing Sioux influence, and which is found also in Sioux songs. This
