Well, interesting but how do we find out if a song is public domain? Is there a formula for "number of years after composition" or something? I have never had to check on this before. I can tell you that Wave was done 45 years ago, in 1967.



Here is PD lIsting: http://www.pdinfo.com/list.php

Works created after 1/1/1978 - life of the longest surviving author plus 70 years - earliest possible PD date is 1/1/2048
Works registered before 1/1/1978 - 95 years from the date copyright was secured.
Works registered before 1/1/1923 - Copyright protection for 75 years has expired and these works are in the public domain.

The only reason I chose Wave as the subject was that I have heard it done at least 10 different ways as far as big band arrangement vs pared down, one rendition did a key change, one bridged out into 1 Note Samba and came back, etc....



Wave is not PD, but it would be cool to hear multiple arrangemetns. Wave is a wonderful creation by Jobim, and it is a shame we can acknowledge that only by listenting to recordings and not by actually play playing it.
