James Hill has released a free ukulele board game called Strumble.
It’s to make practicing more fun but is very practical too, as it splits up working on a piece into: getting yourself familiar with the lyrics; singing the melody of the tune correctly; strumming the rhythm (ie with proper accentuation / dynamics, like you’d use when playing percussion) and changing chords accurately.
I enjoyed listening to him demoing it in episode #29 of his Uketropolis podcast. He picks a song with the Bo Diddley / clave rhythm and shows how focusing on just one or two areas at a time can really help, your performance, instead of rushing in & trying to master it all at once.
I can certainly see how it would be useful splitting up a new tune into sections (e.g. verse, chorus, middle eight) and practicing it this way over a few days. Or when trying to master something tricky. Why not give it a go and see how it works for you?
