Midi files and sheet music for the Ottawa Slow Jam

The Ottawa (Celtic) Slow Jam is a group of 20 or more musicians which meet once a week at the Ottawa Glebe Community Centre to play mainly Irish music with sheet music at a somewhat slower tempo. The original sheet music can be downloaded from the Carp Celtic Jam web site or from this site. Though the sheet music was produced from abc files it was difficult to find the original abc files used to create this set. In addition there is appendix A which appears to be created by scanning various sheet music (printed or handwritten).

In order to create the MIDI files it was necessary to start with the abc notated music. The tunes corresponding to volume 2 were found in the abc file sessionTunes.abc on the http://www.ceolas.org site. In the case of the other volumes, it was necessary to reconstruct the abc music from the sheet music. Time was saved by finding some of these tunes in abc format on the web using John Chambers' tune finder and modifying them if necessary to comply with the sheet music. In many cases bass/chord accompaniment which was missing in the original pdf files was added. This was done to make the MIDI files easier to listen to. A lot of effort was made to ensure that recreated abc music complies exactly with the original sheet music (including page numbering and formatting). A few errors such as missing repeats or misplaced repeats were fixed.

The midi files were created at two different tempos. If you are learning the tunes and wish to play along with the computer, you should download the collection at 96 bpm. A separate collection was created at 144 bpm, to get a better feel for the music. The midi files for all volumes, addendum and appendix have been put in a single folder.

If you are running windows, midisheetmusic is a nice program which allows you to slow down the tempo and displays the sheet music corresponding to the MIDI file. You can get from http://sourceforge.net/projects/midisheetmusic/

OSJindex.xls a spreadsheet listing the tunes and other info. This index is still a work in progress and will contain detailed information on the rhythm and tonality of the music.

I have replaced the collections OSJmidi96_by_title.zip and OSJmidi144_by_title.zip with CCJ_96bpm.zip and CCJ_144bpm.zip which are based on abc file 'CCJ ABC - All Tunes.abc' found on the Carp Celtic Jam web site

    The OSC-appendix.pdf does not preserve the lyrics and some of the bowing markings that were present in the original document.

    Numerous discrepancies between the transcribed and original sheet music were found for the abc,pdf,and midi files in volume 1. A list of the changes are given here.
