This is a bundle pack which includes "Fishing For Pitches" and "Fishing For Chords".
Both of these are music centers to be used with a battery powered fishing game similar to the game called "Let's Go Fishin'" The bottom of the fish should be labeled with the pitches of the musical alphabet.
For "Fishing For Pitches", players will draw a card and read a pitch on the staff. They will race to catch fish matching the pitch on the card.
For "Fishing For Chords", players will draw a card and read a chord on the staff. They will race to fish for the three pitches spelling the chord on their card.
It is best to print the cards double-sided on cardstock and laminate for durability. The original blog post explaining this game can be found at http://musicwithmrsdennis.blogspot.com. Search keyword "fish"
