While many of the marches of Tsarist Russia share similar characteristics with German marches of the period, and indeed some were directly borrowed from Germany (such as "Der Königgrätzer Marsch") and later on France and Austria, the indigenous, pre-revolutionary Russian march has a distinctly Russian sound, with powerful strains in minor keys repeated with low brass with occasional flashes of major chords between sections. The Soviet period produced a large number of modern marches incorporating both Russian themes and structure reminiscent of Dutch marches. Frequently in major keys, Soviet marches often span a wide range of dynamics while maintaining a strong melody well-balanced with the percussion, entering the bombastic range without overpowering percussion as is common with French marches. They are often in the A-B/Cb-A form or ternary form. Agapkin's Farewell of Slavianka is one common example of the classical Russian march, while a notable example of a Soviet-style Russian march is Isaak Dunayevsky's "March of the Enthusiasts" (Марш энтузиастов). Other military marches include the March of 108th Saratov Infantry Regiment and the March of the Defenders of Moscow.
