Program Notes
Conlon Nancarrow (1912-1997) was a fascinating figure
in 20th-century music, spending the majority of his life writing
music for the player piano. Nancarrow was interested in using
the instrument to realize music that was otherwise impossible
to perform. These “Studies for Player Piano” number over 50 individual
pieces, composed over a 40-year period, and demonstrate a wide
variety of interests in musical styles and approaches. Some are
“blues studies” and “boogie woogie suites.” There’s even a “cowboy
tune” (Study No. 6). However, most of them are canons of different
varieties. A large number use different tempo ratios for each
of the voices (i.e. 4:5, 5:6:7:8, 2:¸).
Study 21 is an acceleration canon in which one voice slows down
while the other speeds up until their roles have completely reversed.
To achieve these complex relationships, Nancarrow had to punch
very precise holes in the paper rolls which contained the performance
information that the player piano read. He had a special machine
made just to create these rolls. As one can imagine, this was
a very laborious task.
Technology has made such a job much easier these
days. With MIDI sequencers, composers can “punch” these holes
electronically and change any notes if they don’t work. The adage
“measure twice, cut once” no longer applies. In fact, most sequencing
programs have a piano roll view which allows the composer to view
their material as a “virtual” piano roll. The Yamaha Disklavier
is a MIDI controllable instrument which means that it can be performed
by a computer, receiving performance information from the “virtual”
piano roll.
As a graduate student at Northern Illinois University
late in the Fall semester of 1997 when I learned that the NIU
School of Music acquired three Yamaha Disklaviers earlier that
year and that Conlon Nancarrow had died the preceding August,
it seemed the perfect time to write a piece for this amazing instrument
as a tribute to the late composer. In Homenaje a Nancarrow (Homage
To Nancarrow), I tried to use some of Nancarrow’s ideas but also
utilize technology that was unavailable to him. The result is
a combination of my own original ideas with things which may sound
similar to Nancarrow’s work. There are three main ways that this
piece was composed. Some parts were sequenced—that is, the computer
is given instructions as to what to play, when, how long and for
what duration. The other two methods used were to actually record
a performance into the computer, although the instruments employed
were different. A standard keyboard is an obvious choice, but
more interesting however is the MIDI-guitar. This is simply a
guitar which can convert the vibrations of the strings into MIDI
data which the computer can record and the Disklavier can perform.
This allows the piano to be strummed and to be performed with
the same phrasing that only a guitarist could achieve. In some
cases, these recorded performances are sped up, tweaked and changed.
For example, different notes may be substituted or their register
may be varied upon further repetitions of an idea.
As a young man in 1937, the American-born composer
Conlon Nancarrow went to Spain to fight with the Abraham Lincoln
Brigade against the fascist Franco Government. He spent two years
escaping death and incurred several injuries and illnesses before
he returned home to the US in 1939. After being harassed by the
Federal government about his political associations, Nancarrow
moved to Mexico in 1940, where he lived ever since, eventually
taking Mexican citizenship. Due to these Hispanic associations,
I used a great deal of Spanish-influenced musical materials in
Homenaje a Nancarrow. The composer himself also explored Spanish
music in Study No. 12 and even attempted to emulate flamenco guitars.
