guitar app features

[macmanmatty]

I'm coding a guitar app right now and wondered what features you'd like to see in one. Right now it has a chord calculator where you select an instrument or create your own by entering the number of strings (no maximum number of strings) and tuning and number of frets per string where it will show you all chord formations for a chord you enter aka D Major B Minor E 11th you can also alter the bass of the chord. I have a mode that shows you scales across the fret board from scales you select . I also plan to have the user enter the frets pressed and it tells them the most likely chords. But anything else you think should be added that isn't a tuner (too many goo of those already).

I'm also a programmer. When I was learning music theory, I thought it could be helpful if I do some coding to understand the structure of chords (I always try to learn mechanics this way whenever possible). Months later I extended the little project to a chord lookup utility, but I stopped there after realizing there are simply too many apps for the same purpose, and I'm familiar enough to the chords, so I don't need chord-dict apps any more.

Now the only apps I need is a metronome and a tuner. Although there are bunches of them already, I think there is still some room to be improved. For example, an algorithm could be developed to compensate for the pitch drop of sustains while tuning.

Just checked, my chord dict is still running. You can have a try if you are interested. I didn't bother to make a search interface so the queries have to be sent with raw URL:

Usage: http://123.56.14.211/test/chord/<chord-name>
E.g:
http://123.56.14.211/test/chord/D // D chord
http://123.56.14.211/test/chord/C%23maj7add13 // C#maj7add13, you have to escape the special characters in the chord name

the chord name is parsed on the server side, then the chord and scale diagrams are rendered. Tricky but interesting to make it.

Do you mean you can put a chord in and it will display all the inversions up and down the neck?

That's pretty cool. Is %23 a #?

How about transposing charts, where you can enter the original key and the key you are transposing to and it would display a list of the transposed chords. I can do it in my head, but sometimes when I’m in a huge hurry, it would be nice to have something that would do a quick display so I can just jot them down.

Example: transposing from G to C.... G is C, C is F, em is am, etc.

Yes, you can use an URL Encoder to do the escapes.

That's possible, but there are possibly too many variants. I think a chord-scale diagram will do just fine.

e.g. this is the G7 chord, from the diagram you can see x55767 (xDGDFB, G/D) is a decent inversion.



Also it's very helpful if you want to practise arpeggios.

[macmanmatty]

I though a of a new (possibly useless) feature for this app would allowing for pedals and knee levers like on pedal steel be of use to any one? I planned to have when showing the fret board / scales /*arpeggios buttons that you can press for each pedal / knee lever to show you how the notes change if you add them to pedal steel instrument you create.

how about an app for sight reading notation with note entry directly to the fret board rather than a piano key board (as is done elsewhere)?
