Having analysed the forms of the shapes of the ethnic musical instruments of the mankind, the data of the research leads to the presumption that the musical instruments convey the images of the fauna, mode of life, which reflects on very ancient processes of the humanity. The great part of the images of these instruments shows not only the animal kingdom and tools of everyday life, but also the ancient totemic world outlook and the means of burying – process of traveling to ‘another’ world. These means were canoes, boats and even sea ships. Connection with the water and sea propose the idea about the features concerning two cultures – fishing and shipping. The reflections and relics are evident in the shapes of the ethnic musical instruments of mankind. However, the ‘Sea’ culture is noticeable only in the civilisations of ancient Egypt, Mesopotamia and Greece and in the traditions of using the musical instruments of the current people living in these areas. The ‘Water’ culture relates with fishing in the local rivers and lakes and is evident in the traditions of many nations of the world. The images of the fishing culture are the most noticeable feature of the instruments of the Baltic people.
