Melody Bay
Melody Bay is a part of Tadpole Pond in the game Super Mario RPG: Legend of the Seven Stars. It is home to the composer Toadofsky. Mario can play music here by jumping across on Tadpoles. The bay has lines like a musical score, and the position of a tadpole when Mario jumps on it determines what note is played. From top to bottom, the notes are: Mi, Re, Do, Ti, La, So, Fa. Songs played in Melody Bay are always eight notes long.
Three Songs for Toadofsky
Frogfucius' Suite #18: This is the first song that played for Toadofsky at Melody Bay. Mario must read the poster on Frogfucious's island before attempting to figure out the composition. After playing the correct notes back to Toadofsky, he will reward Mario with the Alto Card.
Moleville Blues: After saving Dyna and Mite when adventuring to Moleville, going back into the area that Croco destroyed reveals several workers. They will want to sing a song and hidden in the lyrics are the notes to the Moleville Blues song, which, when played for Toadofsky, rewards Mario with the Tenor Card.
Monstro Town Star Song: Upon Mario's first arrival to Monstro Town, when he goes in the house where the Monstermama lives, upstairs is a Starslap. If Mario tries talking to it, it will dance a little bit and play a short song which sounds like the tadpoles at Melody Bay. This is the third and final song. However, the one thing that is different this time is the notes do not appear onscreen and Mario must figure the melody out by ear. Playing this song correctly for Toadofsky will reward Mario with the Soprano Card.
Mario and Toadofsky's Original Composition: When completing all three songs for Toadofsky, he will ask Mario to compose an ending for the song. At this point Mario can use any of the 8 notes available to compose an ending for Toadofsky's song. The final song will be a collaboration of all three songs put together with Mario's composed finish piece. Mario can change this ending anytime he wants to.
