Problem: Beginning from the early 1920s composers of both contemporary and popular music wrote for the musical saw. Probably the first was Dmitri Shostakovich.  He included the musical saw, e.g., in the film music for The New Babylon (1929), in The Nose (opera) (1928), and in Lady Macbeth of the Mtsensk District (opera) (1934). Shostakovich and other composers of his time used the term "Flexaton" to mark the musical saw. "Flexaton" just means "to flex a tone"—the saw is flexed to change the pitch. Unfortunately, there exists another instrument called Flexatone, so there has been confusion for a long time. Aram Khachaturian, who knew Shostakovichs music included the musical saw in his Piano Concerto (Khachaturian) (1936) in the second movement. Another composer was the Swiss Arthur Honegger, who included the saw in his opera Antigone (Honegger) in 1924 . The Romanian composer George Enescu used the musical saw at the end of the second act of his opera Œdipe (opera) (1931) to show in an extensive glissando—which begins with the mezzo-soprano and is continued by the saw—the death and ascension of the sphinx killed by Oedipus. The Italian composer Giacinto Scelsi wrote a part for the saw in his quarter-tone piece Quattro pezzi per orchestra (1959). German composer Hans Werner Henze took the saw to characterize the mean hero of his tragical opera Elegy for young lovers (1961). Other composers were Krysztof Penderecki with Fluorescences (1961), De natura sonoris Nr. 2 (1971) and the opera Ubu Rex (1990), Bernd Alois Zimmermann with Stille und Umkehr (1970), George Crumb with Ancient voices of children (1970), John Corigliano with The Mannheim Rocket (2001). Chaya Czernowin used the saw in her opera "PNIMA...Ins Innere" (2000) to represent the character of the grandfather, who is traumatized by the Holocaust. There are Further Leif Segerstam, Hans Zender (orchestration of "5 préludes" by Claude Debussy), Franz Schreker (opera Christophorus) and Oscar Strasnoy (opera Le bal). Russian composer Lera Auerbach wrote for the saw in her ballet The Little Mermaid (2005), in her symphonic poem Dreams and Whispers of Poseidon (2005), in her oratorio "Requiem Dresden – Ode to Peace" (2012), in her Piano Concerto No.1 (2015), in her comic oratorio The Infant Minstrel and His Peculiar Menagerie (2016) and in her violin concerto Nr.4 "NyX – Fractured dreams" (2017).

Problem: The Cham also requested Ming China to intervene by helping bring the Vietnamese back in line by force and demarcate the border between Champa and Vietnam. China, however, only verbally rebuked the Vietnamese for its incursion, which the Vietnamese ignored, proceeding with its attack and plan to destroy its rival. The Vietnamese then carried out its campaign. On November 28, 1470, Le Thanh Tong formally launched his attack as a 100,000-strong Vietnamese naval expedition set out that day, followed by another Vietnamese army consisting of 150,000 men on December 8. The Vietnamese army was reorganized to copy the Chinese army, armed with gunpowder weapons. Le Thanh Tong raised a total of 300,000-strong army in the battlefied and, significantly outnumbering the 100,000-strong Cham army. This came at a massive financial cost since it drained the Vietnamese treasury of 1,000 gold liang each day. However, it decisively won the war.

Problem: In 1554 the Pechenga Monastery was raided by the Swedes. The governor of Novgorod Paletsky sent Nikita Kuzmin to Stockholm to ask for an explanation, but the Russian representative was imprisoned. In response Russia mounted an organized attack with up to 20,000 soldiers in March 1555. With its initially 1,000 men, Finland could not stand against the invading troops, but soon, reinforcements consisting of 3,700 infantrymen and 250 cavalrymen arrived from Sweden. The Finnish nobility had also been engaged in the war, contributing with its cavalry. The goal of the Swedish-Finnish troops was to conquer Oreshek, Korela and Koporye. The siege of Oreshek was badly planned by the Swedish side and failed since the Russians had destroyed the areas surrounding the town and the Swedish troops had insufficient supplies to be able to maintain the siege until the town surrendered. While admiral Johan Brigge besieged and bombarded Oreshek,  the Swedish diplomats tried to find support for their cause in Livonia, Poland-Lithuania and England. Early the following year, 1556, Russia made a new attack, this time with an army almost 20,000 men strong. The attack was aimed at the town of Viborg , and the Swedish troops were unlikely to withstand an army of that considerable size. However, after a few days of pillaging in the area around Viborg, the Russian forces left. The reason for this has not been made clear. Conceivable reasons might be bad discipline or a raging disease among the Russian soldiers. Perhaps it was never the aim to conquer Viborg, only to ravage the areas surrounding the town as a demonstration of power.
