Free chord software for linux

KChords is a guitar chords dsplay and displays chords in graphical form. Now its much clearer how you should put your fingers to paly the chord. The program has a huge list of chords - around 900. If its not enough for you or you want to create a list of your favourite chords you can use chords file editor.

If for some reason you chose to download the source code then you should first extarct
it from the tarball, then run configure, then make install, the usual way:
tar -xzf kchords-0.1.tar.gz
cd kchords-0.1
./configure --prefix=/usr
make install

Attention! You have to use the --prefix, otherwise the program wont find its files
If you encounter any errors or problems during installation proccess please contact me.

Chordpack is a tool written in Perl, whose purpose is to typeset song-books/songs written in chordpro format. The typesetting is done through typesetting system TeX using macro package LaTeX. Chordpack was created to do whatever you might want to do with songs in chordpro format. Chordpack currently can
Generate LaTeX source of songs/songbook
Generate HTML version of songs/songbook
Generate ASCII version of songs/songbook
Generate ASCII version of songs/songbook omitting chords
Transpose chordpro song to desired key
Take ordinary ASCII notation of song with chords and output almost chordpro version.
Enhancements:
- four styles of chord setting
- three styles of song titles setting
- option to chose one or two columns
- option to chose fonts sizes
- on-the-fly transposition to a key with minimum diffic

ChordCast is a Java program designed to help musicians in creating, sharing, and printing chords. It can export chords to HTML documents (using PNG images) for easy publishing. The application is written in English and in French.
Enhancements:
- Drag n drop behavior improved
- Context menus added
- Special or accentuated characters bug fixed
- Several other bug fixes.

PyChoReLib is a Python library which transforms lists of notenames to a chordname. The system uses built-in music theory knowledge to make it easy and quick to add support for new chord types
PyChoReLib, in the current form, accepts a list of note names, and transforms those to a chord.
e.g. [a, c#, e, g] => A7
Inversions are indicated using a slash and the root note.
e.g. [e, g, a, c#] => A7 / E
Main features:
- PyChoReLib can already name and recognize hundreds of chords
- New chords can be taught to the system "by example" e.g. teach the system that [c,e,g] is called C, and using its built-in music knowledge it immediately knows how to recognize and label all major chords in all inversions or (more generally) permutations.
- Once chord recognition definitions have been taught to the system,
- they can be saved to file, allowing for quick initialization of the recognizer
Planned features (planned != promised)
- Extending the chord recognition database with new chord patterns
- Improving the recognition speed for chords with many notes
- Maybe small GUI to allow interactive chord labeling ? Midi keyboard import ?
- Add heuristic rules to recognize more chords, while requiring less teaching
- Add functionality to suggest a scale which can be used to improvise over a chord
Enhancements:
- Dramatic speed-ups in chord teaching and recognition, a new scale recognizer, support for distinguishing modes, a slightly more robust MIDI input demo, and refactoring to avoid code duplication and use Python new-style classes.
- The serialization to XML was removed as it was not useful and didnt work with new-style classes.
- Many bugfixes were made.

Clamor is software for musical ear training. The exercises currently available involve hearing intervals, hearing chords, and hearing notes relative to the tonic or the root of a chord.It runs on Linux and FreeBSD. Its written to be as platform-independent as possible, so it might be easy to port to Windows or MacOS X, but I havent tried. As you see in the version number, this is an early prerelease version.
First, make sure to install the program "sox" and the Perl modules "Audio::Data", "Audio::Play", and "Clone". Probably you want to do use your distros mechanisms for installing the Perl modules, but as a last resort, you can do a "make depend", which will try to use CPANs crufty interface to install the relevant perl modules.
FreeBSD. The ports you need are audio/p5-Audio and devel/p5-Clone. FreeBSD was my original development system, so this should work fine.
Debian. On Debian, youre probably out of luck. Perls Audio module is not in Debians packages, and installing it from the CPAN sources just results in crashes.
Main features:
- The exercises currently available involve hearing intervals, hearing chords, and hearing notes relative to the tonic or the root of a chord.
- Intervals and notes are heard in context: either the tonality is estabished first by playing a cadence, or the note or interval is heard as part of an actual melody.
- The software comes with a synthesizer that uses prerecorded, digitized tones from actual acoustic instruments.

eTcl is a "batteries-included", thread-enabled Tcl/Tk runtime, available as a single standalone executable. eTcl includes several popular extensions (Sqlite, Thread, Zlib, ...), together with a Tcl wrapper for the Pixane image processing library.
Installation:
Just copy executable wherever you want on your device (memory or storage card), and launch it.
- Unobstrusive executable. No registry to set, no external dependencies.
- Standalone executable. Tcl and Tk scripts packed into executable (using VFS). Optimized startup time.
New Tcl user experience on PocketPC
- Optimized for XScale devices
- Faster Arc/Chord/Pie emulation, improved for ARM architecture without FPU
- Efficient WSAAsyncSelect() emulation. Sockets, and fileevents on sockets, should be fully functionnal (in both client and server modes)
- Support for native menu
- Improved native look and feel.
- Windows Mobile specific extension: manage SIP, change (X) button action (closing Correct handling of mouse (actually touchscreen) events
- Support for intercepting hotkeys (calendar, notes, etc...)
- New porting approach, based on very minor changes to generic Win32 port (and no changes to generic part of Tcl/Tk distrib).
- Patch to Tcl or Tk distribution is only few kilobytes large, everything else has been moved into a minimal emulation library. This should allow us to keep synced with future Tcl/Tk release.
- Easy build process. Nothing but Evc4 and a native Tcl interpreter required to build binaries for all target architectures supported by Evc (Cygwin, external libraries, etc... not required)
- Works fine into Microsoft Pocket PC 2003 Emulator. Debugging code made easier
Included native extensions:
- Pixane: script your image transformation, support for reading and writing several popular image formats (PNG, JPEG), support for TrueType fonts
- Sqlite 3: a self-contained, embeddable, zero-configuration SQL database engine
- Zlib: native deflate/inflate support
- Zipfs: easily Mount your ZIP files into Tcl Virtual Filesystem
Included Pure Tcl extensions:
- EvoTcl: A very large set of tcl utilities (OOP, Database, HTML/XML parsing, ...). See http://www.evolane.com/software/evotcl/
Enhancements:
- This release focuses on performance optimization (especially for WinCE) and code stabilization.
- It adds support for reading tclkits, together with an automatic tclkit to eTcl kit converter.
- It embeds up-to-date versions of several built-in packages, such as sqlite 3.4.1, libpng 1.2.18, and tile and tkhtml3 CVS snapshots.
- Tile has been moved into the normal version.
- The Mac OS X bundle declares associations so eTcl kits can be launched directly from the Finder.
- Binaries for linux-powerpc have been made compatible with Linux on Playstation 3.

The Circle is an open source scalable decentralized peer to peer application. What does that mean? Well, theres no central authority running the show. No entry taxes either, no censorship, and (in theory) no weak point which can break the whole system. No one even owns the source code. There is a network, even if there are a few people which uses this program.

The Circle allows you to :

* Share files
* Send instant messages and chat IRC-style
* Put together your own personalized, trust based news service
* Proxy Debian package downloads

The Circle is written in Python. It runs on Linux and Windows. (in fact, there is very little operating system specific code, so it will most likely work on any system that supports Python).

At the core of the Circle is a decentralized hashtable, or "Chord". This table allows users to search for files in logarithmic time, based on keywords. This means that the Circle does not have the scalability problems of Gnutella style network (such as Kazaa, eDonkey), while also avoiding the need for a central server and therefore a single point of failure. Details of its operation are given in the "Technical Details" section below.

The Circle does have the ability to post fully anonymous news a la Freenet. However, the file-sharing protocol isnt entirely anonymous. People will be able to work out your IP address.

In order to protect user privacy, the Circle includes a Digital Rights Management system. Although everybody can search your files by their keywords, you may choose which users are authorized to download them. An unauthorized third party has access only to the names of your files, not to their content. Needless to say, we expect you to use this system in order to prevent copyright infringement, while allowing private copy.

Note: If we become aware that you are trying to share snuff or child pornography, we will be able to work out your IP and from that your location and identity, and report you to the police and/or your ISP. Snuff and child pornography are things we think any reasonable person considers to be evil (its an issue quite separate from the debate over copyright).
