Most of what I know about teaching Spanish I learnt from Tracy years ago, and I am eternally grateful for that. One of those things is the importance of music in the classroom as a teaching tool. Sure, we learn songs and watch YouTube videos, but a lesser-known quality of music is as a mnemonic tool.
It is a well-known fact that irregular verbs in any language are difficult to memorize; there are so many! They are so hard! So, one way of helping to learn and memorize them is with songs, even if they are silly, basic melodies.
Here are a couple of examples of using basic melodies to help memorize irregular verbs: one is for the past tense preterit, and the other one for affirmative “tú” commands. Enjoy.
