This is such a wonderful project! I would absolutely love to transcribe the song you've created for your boys.
I am a university trained musician with extensive songwriting and recording experience. My areas of proficiency include voice, piano, flute, saxophone, guitar and composition. I am positive that I can quickly and correctly transcribe your song. I will deliver the finished product in the file format of your choice and also provide you with a midi sound file of the melody. For a small fee, I can compose an instrumental accompaniment for the song.
Please allow me to complete this project for you, I would love to be involved in the beautiful tradition you've started!
