Before I "reinvent" the wheel, I have a need for a chord player program for a standard Windows XP/Vista/Windows 7 desktop PC. I'll get to the preferred specification in a moment, but please first look at this mock-up I've made:

Right, so the idea is as follows:

User (e.g. me) plays a note on the keyboard by clicking with the mouse.

The corresponding note appears on the staff.

The next note builds a chord with the first. The mock-up shows a chord comprising four notes.

Each time a new note is added to the staff, it sounds (e.g. through MIDI) so that user has audible confirmation.

To hear the whole chord, click the requisite button. The chord must play immediately. If the chord is changed (see below), the new chord must also be heard immediately the button is clicked. Thus, I place a few notes on to the staff, click Play Chord, modify the chord, click again, and so on and through a process of trial and error I arrive at the chord I'm trying to match when listening to a recording.

To change the chord, highlight (with the mouse) one of the notes and drag/drop it to a different staff line. Again, the note is sounded each time it is repositioned. Alternatively, the whole chord is re-sounded each time a note is repositioned.

Notes should be removable, e.g. highlight note and press Delete button on PC keyboard.

Now, the big question is: Has something like this already been produced? I have the various components from my Tunefinder program and other programs to create this new one, but we're talking about weeks of programming here, as it's not a trivial task.

I don't think anything that specific has been developed, however there are some iPad apps that do similar things:

1. Tenuto has a "Chord Calculator" feature - specify a bottom note and the type of chord you want to build above that note. Click on it to play it or click any of the buttons below to adjust and hear the difference. It also has an "Analysis Calculator" - useful for things like figured bass and harmonic analysis.

2. I think Piano Note Pro might accept MIDI input to test notes and chords that are shown on the screen.

Perhaps a combination of these apps could be a good starting point for your research!

I have now completed my new application, VuChord, having not found anything suitable for a Windows PC. Read about it on my web page at http://www.littletyke.myzen.co.uk/lt/html/vuchord.html. You can download the application from http://www.littletyke.myzen.co.uk/lt/VuChord.zip. There is no installation procedure (apart from the public domain music font). The Readme.rtf file explains everything. It also includes a feedback link if you have any comments, suggestions or gripes. Or you can add a reply to this thread!

Moderators: Please feel free to move this thread to a different forum if you think the 'Teacher' forum is not appropriate.

What is the purpose of the application? I'm having trouble understanding what the practical use would be.

(Put another way, if one wanted to know what a collection of notes sounded like, why not just play them on a keyboard?)

Kreisler, if you go to this page in the Piano World Forums:
http://www.pianoworld.com/forum/ubbthreads.php/topics/1136799/3.html and scroll down to my post dated 1st Feb 2010, you'll see a link to my first attempt at transcribing an old recording of Charlie Kunz's playing style. I used the Widi Soft Audio to MIDI Converter software to do this. The raw transcription wasn't too good, with hundreds of stray notes as Widi tried to make sense of the various overtones in the mp3, so I edited the resultant MIDI file heavily in a music notation application to remove or modify some of Widi's wilder guesswork.

There's still a lot of improvement needed and to do that I need to analyse some of the chord progressions in as fine a detail as possible.

And thus I hit upon the idea of VuChord. It's a project that has been on the back burner for three years, then last October a heart attack intervened, and then triple bypass surgery in March 2013. Now that I'm well on the road to recovery, I thought I'd resurrect that project, and thus VuChord finally sees the light of day! It's very much a prototype, but it is already helping quite a bit with the transcriptions.

There may be other applications out there for the modern iPad/iPhone-type gizmos, but I don't possess one of those. I only have Desktop PCs and extensive searching in Google didn't reveal any other app that was suitable.

Further enhancements to VuChord would include:
- Building a progression from several sequential chords.
- Copying the chord(s) to a music notation program, e.g. Finale.
- Saving a chord progression so that one could work on it again later.
