Play in Harmony Mystery Cache

Let's make music together!

This cache was created to combine our loves of geocaching and all things musical. For this challenge you will need to use your ears, your eyes and your brain (or a trusty calculator!) 

Note: The cache is not at the listed coordinates.It is hidden with permission within Jervis Bay National Park. It covers the north and west shores of Jervis Bay, parts of St. Georges Basin, Lake Wollumboola and ocean beaches. It is famously renowned for its white sandy beaches, the result of a high silicon content, and the very clear waters of the bay. Habitats in the park are many and varied, including forests, woodlands, heaths and wetland. Some species include blackbutt, ironbark, swamp mahogany, paperbarks, banksia, tea tree and wattle. A number of threatened plant habitats are also protected in the park, including Littorial Rainforest, Coastal Saltmarsh, Swamp Oak Floodplain Forest and Bangalay Sand Forest. Native animals that may be seen in the area include parrots, black cockatoos, yellow-bellied gliders, bats, possums and kangaroos. There are also some vulnerable bird species such as the great knot and the pied and sooty oystercatchers, as well as the powerful owl. To solve this puzzle and find the cache, you will need to listen to the track which will play a series of musical notes. You will need to decipher what you hear into coordinate numbers. A musical note, or letter, will correspond with a number. So A = 1, B = 2 and so on. 

Now they say music and maths go hand in hand, so lets test out the theory! 

To make things a bit trickier, once you have your numbers worked out:

Subtract 9800 from the first 7 numbers on the track for the South Coordinates.

Subtract 101000 from the last 8 numbers on the track for the East Coordinates.

The cache is a large sistema container filled with musical goodies for the first to find. Please replace exactly as found.
