not my melody, just a few things to talk about

Here we have a musical score written on music paper or a sheet of music paper.  We have the treble and bass clefts  with the key signature of A major and in the first measure, only, the time signature of 4/4 time.  Each quarter note gets one beat and there being four beats to the measure.   Note that the first measure has two beats, not four.  And that there is a half rest in the bass cleft.  There is a small p in the third measure, which tells you how you will play those descending notes emotionally.  This is called Dynamics in music.  The small p stands for the Italian pianissimo and means that you would play this softly.  Notice the mf in the first measure, this also means play the piano moderately soft.  I consider these to be music trivia, because different instrumentalist play around with these interpretations.
