Brief:
You are required to design an interactive mobile application for an educational game based on the specification provided. The purpose of this exercise is for you to demonstrate your ability to design a usable, interactive paper-based prototype, which can be used as part of a usability study.

1. Specify it:
Use a user-centred design methodology. Include a user analysis, task analysis, functional analysis, environmental analysis.

2. Design it:
The application is intended to be well structured and presented, and you are to produce the paper-based prototype.

You are to justify each design decision with reference to both the research, as well as the design guidelines. The aim of the exercise is to say WHY the design feature works, and not just WHAT the design feature is. Include layout, images, colour, and navigation.

3. Test it: Usability study
Get feedback on your design. Establish a set of heuristics and evaluate the design with colleagues. Get them to try out the prototype and log the results.

4. Evaluate.
5. Include a reference list. Ensure you are referencing BOOKS as well as the web…
SPECIFICATION
This application should allow the user to make music. It should provide an accessible way to demonstrate instrumentation, rhythm, melody and harmony. The interface should be fun and easy to use. Users should be able to create a tune in seconds. The app is aimed at children and enables them to use patterns or colour to compose a tune. Users will be able to express their creativity, learn the fundamentals of music composition and increase their music appreciation.

The way it should work:

BUILDING A SONG…
1. Create a melody using a sketch pad
• Create a simple tune/melody. Simply tap and drag to create, and edit notes OR
• Connect visual patterns with sounds using a colourful, intuitive interface

2. Add an orchestra
• Build an ensemble from various instruments without complicated menus of settings

3. Play back the composition
• Hear your song
The system should take into account music theory principles to make sure the music sounds harmonious.

WITHIN AN ENVIRONMENT
1. There should be 8 different sketch pads. Each sketchpad has a character. Each has its own unique sound.
2. Within each sketchpad the user should be able to create a tune, add instruments and play back the song.

AND ADDING THE INSTRUMENTS
1. All the instruments must be able to be played individually
2. There should be samples of rock and pop to orchestral for each instrument
3. There should be a way of to experiment with instruments in five categories – Keyboards, Strings, Woodwind, Brass, and Voices!
4. There will the ability to master drums and percussion instruments from around the world.
