My Resonance FM broadcast next week will be called Musica Practica, which is also a working title for the text I wrote about yesterday. Below is the full text as it stands at the moment.

The materials you need to commandeer the frequencies of short-wave radio stations are things you probably already own. You can make the transmitter part small enough to carry with you to somewhere high up above the buildings. Then you can turn the transmitter on and the people in the buildings you can see can hear you. First you can tell them there are certain materials they probably own or can find in the buildings they are inhabiting, and that while you give them a fairly small pause they can collect them.

After the small pause you can tell the inhabitants how to make constructions from these materials that can make rhythms when they are moved or tapped in certain ways. You can tell them how to make a number of these constructions, and because some of the methods can be fairly complicated you can give them a larger pause than before to assemble them.

Then you can tell them they can synchronize the second hands of their clocks with yours, so that when they begin to play they can stay in time with one another. After that you can tell them each to tap a construction a certain number of times each second to tap a rhythm. You can tell the inhabitants to stop tapping the rhythm after a while and then you can put them into a number of groups so that there are a number of smaller parts, and then you can give each smaller part a rhythm of its own to tap.

You can describe each rhythm by telling the inhabitants how many taps to make each second, and you can rely for timing on the synchronized second hands of your clocks. In this way you can almost altogether avoid being part of the sound, apart from the beat you have to give to count the inhabitants in, which you can try to make quiet and very brief. You can describe the rhythms to one part at a time, and if you count in each part after you have told them what to play, the general rhythm of all the parts together can become fairly complicated as you continue to speak.
From time to time while the inhabitants play this rhythm, you can tell some of the parts to stop playing, and you can describe how they can make alterations to their constructions so they make slightly different sounds. You can give them a small pause to make these changes, and then you can count them back in to the general rhythm.

You can give certain inhabitants new instructions to amend their constructions while the remaining inhabitants continue to play. You can tell them how to make their constructions play melodies as well as rhythms, and because the instructions can be fairly complicated, you can give them a pause longer than the last pause to make the amendments.

Then you can start to group the amended inhabitants into a number of parts and tell each part the names and orders of certain musical notes part by part, and you can tell them how many beats they can have in each second. Part by part you can count each group briefly and very quietly back into the general song and when you have told everyone to play there can be applause.
