For this game, give each person in the group an instrument to play. One person should then decide upon a scene for the group to attempt to convey through the playing of music. Scenes could include cats fighting, a rain or thunderstorm, a busy marketplace or the sun setting. You can also use emotions as a concept for the musicians, such as fear, happiness or regret. Once the person has decided on a concept, he should say it out loud for the rest of the group to hear. The group can then begin to play. The members of the group can take turns in deciding upon the theme of the music.
To play this game, give each member of the group an instrument to play. One member of the group should play a few bars of music, which she should make up as she plays. The rest of the group must then copy the notes and rhythm of the music played. The person leading the game should make sure that she adapts the complexity of the music they play according to the skill level of the other members of the group.
A group can play "Twisting Music" by taking a written piece of music and changing it through improvisation. To achieve this, switch notes around, alter the key and repeat sections of the music. Each member of the group should give an idea as to how they can alter the music and then the whole group can play the piece of music.
There are no rules for free improvisation, although it generally works best if each member of the group plays a different instrument. All members of the group should listen to one another as they play while also aiming to use an individual style that allows them to stand out from the group. Members of the group do not have to play constantly, and people can also swap instruments during the game. Another variation of free improvisation is to provide each member of the group with an instrument which they do not know how to play.
