Melody is a simply notion of a music ludic feature that can be exploited further. By flowing the melody, the player completes the melody by entering simplified notes (without considering inputting intervals larger than an octave or key signatures).
Melody intends to bring simple pleasure and challenge to music lovers not by means of “twitch gameplay” (action) but by music cognitions, which attempts the more “melodic” mechanics of music games .
Here is a demo video:
I can think of a decent library of various genres of music available for a melody game like this. Variations of gameplay can be exploited.
Mixed music pieces in one game session;
Complete the melody in a backward order (of each melody question and answer);
A “campaign” of music history and evolution/movements;
Realistic mode including accidentals–12 tones (Ha, Schoenberg~)
