I created a modal song many years ago. I have just created a simple videoclip with my singing and words. Simple and easy to remember tune. My pupils enjoy it and remember the modals easily. I hope this is useful to you too. I uploaded to youtube for free usage. Not a commercial product and nothing for me to sell. Just a teacher sharing for other teachers who may find it useful and relevant.
