Magnus-Opus: Number Check
You may be inadvertently performing one of the Magnus-Opus melody series each time you use your telecommunications device (telephone, mobile telephone, modem and other internet devices).
In order to ascertain if you are in breach of international copyright law you may enter any alpha-numeric sequence you may be using via your telecommunications device in our dialogue box below. This will compare your number with our melody database. If your number should match one of our compositions the melody and opus number will be displayed. You should then complete a licence agreement as soon as possible.
