SongTrellis Tunetext URLs describe musical scores. When a tunetext
URL is loaded into a web browser, the SongTrellis server prepares
a MIDI performance of the score, which is performed as a background sound,
and prepares a matching printable score, which is displayed within a
window as the MIDI performance plays.
Score preparation and display for a Tunetext URL is usually
completed in the fraction of a second after the URL is launched in a web
browser..
Because the score is entirely described by a list of parameters encoded as
string of alphanumeric symbols, once the syntax of Tuntext URLs are understood,
it is possible to quickly change the peformance
(tempo, instrumentation, volume) and display of the score (type of staff, the
selection of voices displayed in the score, score coloring by melodic interval,
harmonic interval and pitch class).
The pitches and durations of each note, rest, and chord are visible in a tunetext
URL and may be changed by editing their description iwithin the URL.
Links are also presented within this window which can produce
HTML directives, which when copied into a webpage can cause
the score to be performed in various ways.
Links are provided to produce HTML for four different score
preentations.
The first presentation plays the score when the containing web page
is loaded.
The second presentation provides a controller which allows the
user to play the score from beginning to end when the controller's play button is pressed.
The third presentation provides a controller
which loops the entire score when the controller's play button is pressed.
The fourth presentation displays the the score image as a button.
When the user clicks on the score image, a tunetext panel is launched
which performs the score, This presentation allows for a musical idea
to be transmitted easily around the web via web pages and via email.
Demonstration links are provided next to each HTML production link to show
how each presentation format operates within a webpage.
Email links are also provided to allow a user to email the MIDI sequence, printable score
and example HTML to their mailbox, so that the score can be installed on their
own webpages.
At the bottom of a tunetext page a link is provided to copy the entire tunetext
to the end of the user's workscore on the SongTrellis site, if they are logged in as
a SongTrellis user.
