mChorder - Your Musical Instractor

Trying to keep our project inside defined theme, we decided to make application that will be targeted to those people, who just started playing guitar and are needy of basic knowledge. Also, at the same time, while we were developing application, we were also paying attention to user state, and what experience user will get. One of main parts was to provide easy interface for user, taking in consideration that while playing on guitar, only one hand is free and it already limits features. Additionaly, information from screen have to be easily readable, and to provide that we were interviewing other student to make sure that GUI is best possible. As the project is aimed to people that just started to play, it includes only necessary amount of chords and scale.


Result of coding is application “mChorder”.

The Chords in use:

      self.chords = ["A", "B", "C", "D", "E", "F", "G"]
      self.scales = ["Maj", "Min", "sMaj", "sMin"]

The current user interface of mChorder was a result of user interviews. At first we had few different models for the User Interface.
