    Input arguments or piped data which are expected to be Humdrum files can also be web addresses. For example, if a program can process files like this:
           program file.krn
    It can also read the data over the web:
    Piped data works in a somewhat similar manner:
           cat file.krn | program
    is equivalent to a web file using ths form:
           echo | program

    Besides the http:// protocol, there is another special resource indicator prefix called humdrum:// which downloads data from the kernscores website. For example, using the URI humdrum://brandenburg/bwv1046a.krn:

          program humdrum://brandenburg/bwv1046a.krn
    will download the URL:
    Which is found in the Musedata Bach Brandenburg Concerto collection.

    This online-access of Humdrum data can also interface with the classical Humdrum Toolkit commands by using humcat to download the data from the kernscores website. For example, try the command pipeline:

          humcat humdrum://brandenburg/bwv1046a.krn | census -k


    The pitchmix program is related to the Humdrum Tool scramble.
