Play By Ear

Play By Ear is one of the many souvenirs a player can obtain in WarioWare: Touched!. By blowing into the Nintendo DS microphone, players can play a harmonica. It is one of the few instances where the game receives button input, with the face buttons changing the pitch of the harmonica. The souvenir uses the same graphics as Sweet Nothings.
