You can download Tune Smithy's Chord Progression Player and use it to play any chord progression using the normal symbols for chords, jazz chords etc. Just paste the chord progression into the box and immediately hear what it sounds like.
(screen shot, doesn't play notes - to try it out you need to download tune smithy)
All you need to do is to paste a chord progression into the Progression windowand press the play button to hear it. The = signs can be used to repeat a chord.
The Ed. button opens another window with more space for the chord progression.
You can also set a rhythm for your progression, using O, o, . etc for various sizes of beat, and V100, v50 etc to vary the volumes:
It recognises roman numerals (popular and classical) and note letter type progressions. Recognises complex jazz chords like Csus2, C9, Cdim7 Cadd4, cmM7 etc.
There are many sites that list chord progressions - and you can just copy and paste the progressions into the player to hear them.
Here is a screen shot of a test of some of the chord symbols it recognises: C, Cm, Csus2, Csus4, Cadd2, Cadd9, Cadd4, Cmadd2, Cmadd9, Cmadd4, Cadd2add4, Cmadd2add4, Caug, Cdim, Cdim7, C5, C6, Cm6, C6/9, Cm6/9, C6/7, Cm6/7, Cmaj6/7, C7, Cm7, Cmaj7, C7sus4, C7sus2, C7add4, Cm7add4, C9, Cm9, Cmaj9, C9sus4, C11, Cm11, Cmaj11, C13, Cm13, Cmaj13, C13sus4, Cmmaj7, CmM7, Cmmaj9, CmM9, C7#9, C7b9, C7#5, C7b5, Cm7#5, Cm7b5, Cmaj7#5, Cmaj7b5, C9#5, C9b5, C7aug9, C7dim9, C7aug5, C7dim5, Cm7aug5, Cm7dim5, Cmaj7aug5, Cmaj7dim5, C9aug5, C9dim5.
(some are repetitions of the same chord spelt differently). You can also use chord symbols in Roman Numerals type notation (V7, ii7 etc) - in the popular form or the classical form.
Here is a clip of it playing them all (with the repetitions for the different spellings of the same chord):
The player will also recognise any other chord symbols you make up along the same lines, so basically just about any chord symbol you type into it. If there is a symbol it can't play just let me know and I will see what I can do to add it in.
It also recognises various chord symbols to help with playing microtonal chords , such as Csm for the septimal minor or Ch9 for a harmonic ninth chord etc. (Later I plan to add in Sagittal chord symbols as well, which will let you play just about any microtonal chord).
If you have a favourite chord symbol not included e-mail the developer and ask for it to be included: support@tunesmithy.co.uk
You can also set various styles of playback. Here is the Greensleeves chords progression played with broken chords and a figuration for the arpeggiation pattern
That particular clip is played in just intonation - so the intervals are all pure harmonic series based chords - frequencies are all in ratios such as 5/4 (e.g. 400 Hz and 500 Hz or whatever).
In this type of tuning, the scale needs to be retuned for each chord if you want them all to be pure - because normally only a few chords can be pure just intonation in any scale. Most tuning systems such as twelve tone tunings are compromises that let you make some chords pure and others impure.
In this case the clip uses the option Rotate scale to chord roots which you see in the screen shot at the top of this page. The chords themselves are wonderfully pure, but it has disadvantages too - to achieve that you need to have tiny shifts in pitch of some of the notes as the tune progresses - something that some people find more noticeable than others. If it sounds out of tune to you in places, probably you are noticing those tiny shifts in pitch from one chord to the next, rather than the pitch relationships between the notes in play at any given time, which are beatifully in tune. Anyway this is one of the things you can explore in the Chord Player.
Using exactly the same chord progression and changing the scale to a septimal one with the so called subminor (7/6 for the third) and supermajor (9/7 for the third) you have the darker more soulful
You can listen to what your progression sounds like in any temperament. The drop list includes some famous historical ones. If you follow the links in the menu you find more and then you can also use the Scala scales archive of over 3000 scales, many of which are twelve tone scales, which you get if you install the Scala archive.
You can also use scales with more than 12 notes to an octave, such as thirty one equal for instance. When you do that, the Chord Player plays the closest available pitches. You can also use a few microtonal notations which are built in to the player.
You can also set up your own system of chord symbols to play a progression in any tuning you like - though that last aspect is something that will be developed fully later when I hope to add in support for the etensive Scala chords list.
Another development for the future is to add in the Sagittal notation system to the player, for use in the chord symbols.
The Chord Player itself is free when used just to play the chords - with a short splash screen when the program starts up.
If you record to midi while the progression is playing, then that's a shareware feature. However, with the free player, you can record up to five midi files per session - you just need to exit from the player and start it up again when you go beyond that limit. With each midi file you can record up to one minute.
Any of the shareware levels will unlock the Save Midi feature to permit midi recordings as long as you like and any number of midi files per session, also remove the splash.
If you want to use your chord progressions with the fractal tunes, you will want the Play level, which also unlocks the Midi Save level.
