Alone or in a team, try to discover well-known songs by humming them based on imposed onomatopoeia! A kind of original Blind Test in which it is the players who hum the melodies to be guessed!
The onomatopoeia imposed on the players requires them to read and concentrate while having to hold a melody.
This small cognitive overload causes a loss of accuracy which gradually returns, when the player insists.
During the 30 seconds dedicated, the other players have the sensation of having the title of the song "on the tip of their tongue".
