A warm, rich tone is the key to the opening excerpt in A major. Make sure you articulate exactly as written in the music - do not add extra slurs. The first breath should come after measure 4, between the E half note and the first F# of measure 5. The next breath should be after the fermata. The turn, which is the squiggly symbol above the A in measure 8, is an ornament that should be played this way: A-B-A-G#-A, with a longer emphasis on the first A in the sequence. Be sure to tongue the B after the turn.
In the second short piece, marked quarter note = 112, be sure again to articulate exactly as marked. The mf marking indicates that you can play out. Count the rests in this section carefully, and practice with a metronome.
The third piece, in 6/8 time, shows off the high range. Do not be shy about giving plenty of air support to these upper register notes - if they are supported properly, they will speak with a lot of sound! That is okay as long as you support all the other mid-range pitches in the melody. Follow the dynamics exactly. For measures 36-37, crescendo to a mf or f and then drop down to mp at measure 38. Be careful to not go flat on the last note in measure 42.
The last small piece has some deliberate tricks with the articulation. Be sure to articulate the eighth notes in measure 45 but slur into the one eighth note in measure 47. Check with your metronome to make sure that your eighth notes in measure 50 relate exactly with the sixteenth notes in measures 51-53. Do not rush the eighth notes in m. 50 or you might end up in real trouble with sixteenth notes that are too fast at the end.
Always keep a beautiful tone throughout the entire page, and endeavor to keep a consistent tempo through each piece.
