It is well known that domestic animals get nervous when the sun sets.
Some might even bite, or turn aggressive towards whoever is nearby. Music is a magic remedy for these situations but we must remember that all species have their favorite singers or players. Also, some instruments are to be avoided, except for special players: for example, the use of a violin or viola should be reserved for Kim Kashkashian or Pinchas Zukerman.
If you are not familiar with classical players, it would be better to play some famous singers, like Caetano Veloso, Charles Trenet, Joan Manuel Serrat or The Beatles. It might happen that your pet is deaf…You should play in this case, loudly, any of Beethoven's Symphonies. Combined with this mask, the effect will be terrific!
