Program Notes

“Wiki-Piano.Net” is piece for piano and the internet community. It is composed by everyone. At every time. The composition is notated as an editable Wiki internet page and is subject to constant change and fluctuation. When visiting the website everybody can see the current state of the piece and make alterations. The website allows the visitor to place media content, comments, audio and picture in the piece as well as traditional score editing.

The concert performances of the piece take the current state of the website as the score. Hence no performance will ever be the same. Through the editing process of the community new versions of the piece will constantly evolve.

Information for Performers

In order to perform the piece you use the webpage as the score and perform the current (or almost current) version of the score. For this you use the performance mode of the website: This mode displays the score in a more readable fashion. You can use a foot pedal to jump from section to section so that no interaction with the laptop is necessary. A second browser window is synchronized with the web score and displays all media content (like embedded video etc.). This second window is displayed on the projector and can be accessed through So all performance materials of the piece are part of the website and accessible by everybody. A detailed tech rider for the piece can be found here.

The performer interprets the score in the concert situation. That means: Everything that is on the score at that time will be played, shown, read and performed. No parts are left out and no parts are added. Only the user-generated content will be presented in the concert. But the performer is invited to interpret the passages. This means, that the timing can be chosen by the player, as well as the way in which the text is presented. The player is also free to underline non-musical passages with piano / sound. The sole role should be that the content of the online community is presented well in a concert form. Hence musical interpretation is encouraged, but should support the existing score and not change it.

Personal Data

The user of the website needs to log in with any user name in order to edit the page. This name can be arbitrary and does not need to be the user’s real name. The only reason for the login is to prevent bots from editing the page. The name and password will not be used for anything else.
If you should provide your real name in the feedback section or in the text fields, then this information will only be used to be displayed on the website and in the presentation of the piece in concert. There is no other usage of that data.
Some statistical (no personal) data is analyzed with the Matomo analytics tool. Acquired information (like country, browser, editing times) are not linked to real names and personal data. They are not used for any commercial or other purpose than optimizing the web page use. This feature can be turned off at the bottom of this page!
