The key of the week is G Major!
Long notes in G Major, 2 octaves, looking for the most resonant and beautiful tone for each note, all the way to the high G. The high G appears occasionally in the literature, nd while high, it is not impossible... besides, if you practice playing up to the G, the notes above high D are not that scary anymore...
Tuning: Major triads along the G Major scale, with your tuner providing a drone on the tonic of each chord. My favorite all-purpose temperament is currently 1/6 comma meantone. Valotti also work, and equal temperament if you don't have other options.
