String Register is a memory card game about matching training strings to musical notes. Step into the role of a piano tuner preparing for a shift, turn over two cards at a time, and recall which string belongs with each note. The exercise uses its own numbered training strings and note labels such as C4 and D4.
Choose from three registers with progressively larger sets: Middle register has four pairs, Extended register has six, and Upper register has eight. Each pair connects a string label with its corresponding note. Matched cards stay face up, while mismatched cards turn back over after a short pause. Every register has a fixed layout, so replaying gives you another opportunity to remember the same positions and associations.
Follow your found pairs, moves, and elapsed time as you clear the board. The timer starts when you reveal your first card, and completing the final pair brings up your result in moves and seconds. Replay the register or choose another set to practice. Completed registers and your string guide preference are saved on your device. Use the optional guide to keep the meaning of the exercise’s string numbers close at hand.
Match training strings to notes and test your memory across three registers.
