There are various tricks, but I don't think any of them are particularly useful. ("Think in treble clef, then transpose down a major ninth...") Tenor clef isn't any harder than treble or bass clef--just less familiar for most of us. Practice your Milde and Weissenborn etudes until tenor clef becomes automatic! (Then start relearning to play in bass clef.)

Good luck,

Every single sentence here is 100% true. Make that 110%. Even the part about relearning bass clef.
