Upon arising, I tune my instrument. The practice of Qi Gong, followed by meditation, and a petition for help, harmonizes the tuning. Instruments are sensitive to the conditions to which they are subjected. The tuning needs to be checked and adjusted throughout the performance of the day. Failure to take care of the instrument will compromise the tone. The action of the instrument suffers, and ultimately the music of life cannot be played.
Sometimes the adjustments to the instrument are more than the musician can tend to. Certain venues place unusual stress on their functioning. If one continues to subject the instrument to harsh conditions, additional help must be sought or damage may be done to the instrument. Time to connect with the Luthier?
