The front-line musical instruments were created only by heroic Korea thanks to the defenders of the country in the 1950s who cherished the revolutionary optimism. They are unprecedented in the histories of world music and world wars.

The history of the front-line musical instruments started at the time when the KPA transited to a positive positional defence according to the strategic intention of the Supreme Headquarters.

The People's Army soldiers of Pakdal Pass in the eastern front cut and trimmed the lower part of trees which were burnt by the enemy's bombardment, and made a flute, a simple musical instrument. They cultivated patriotism, picturing their native places and mountains and rivers and seething with the hatred for the enemy from the sound of flute

President Kim Il Sung valued the optimism of the soldiers who are singing songs of victory with the musical instruments made by themselves and gave instructions to quickly disseminate and popularize the front-line musical instruments in the units so that the song of victory resounded and revolutionary optimism prevailed on the fighting heights.

Thus, the front-line musical instruments were made on a full scale on heights of the whole front in the period of the fourth stage of the war (June 11, 1951-July 27, 1953).

The KPA soldiers had no wood or other materials for making musical instruments because of the enemy's bombing. But they substituted enemy's parachute lines and communication lines for stringed instruments and made musical instruments with various kinds of empty cartridges and bottles.

The greatest number of front-line musical instruments were made on Height 1211 where bullets and shells showered further than other heights and battles decisive of life and death were ceaseless.

The brave fighters of the height made musical instruments and played the first melody with the immortal revolutionary hymn "Song of General Kim Il Sung".

Now, the front-line musical instruments which are displayed at the Victorious Fatherland Liberation War Museum implant in the visitors' mind the revolutionary truth that the might of the revolutionary optimism is inexhaustible.
