import music

tune = ["C4:4", "D4:4", "E4:4", "C4:4", "C4:4", "D4:4", "E4:4", "C4:4",
        "E4:4", "F4:4", "G4:8", "E4:4", "F4:4", "G4:8"]

import music
# Continuous alarm sound, high, low
while True:
    for freq in range(880, 1760, 16):
        music.pitch (FREQ, . 6 ) # frequency, the delay in milliseconds
     for FREQ in Range (1760, 880, -16 ):
        music.pitch(freq, 6)
