Used by the routines at Handle_Sabreman_Jumping and Handle_Collectable.
Plays 10 tones of one cycle each. The half period of each tone is the counter multiplied by 10 and exclusive ORed with 1C.

||||
| SoundsSword | A0E4 | LD D,$10 | Set the number of tones to 10. | |
| SoundsSword_Loop | A0E6 | LD A,D | Fetch the tone counter, which is used to work out the half period of the tone. | |
| A0E7 | RLCA | Rotate it left twice. | ||
| A0E8 | RLCA | |||
| A0E9 | XOR %00000111 | Flip the low three bits. | ||
| A0EB | RLCA | Rotate it left twice again, which makes the half period. | ||
| A0EC | RLCA | |||
| A0ED | LD B,A | Store the half period in B. | ||
| A0EE | CALL SoundsClick | Play the tone. | ||
| A0F1 | DEC D | Decrease the tone counter and loop back until all of the tones have been played. | ||
| A0F2 | JR NZ,SoundsSword_Loop | |||
| A0F4 | RET | Return. | ||
