Acemaşiran Makamı: The Çârgâh Scale in the Low Register

Acemaşiran is one of the oldest continuously performed makams in the Turkish tradition, with a documented history spanning roughly four and a half centuries. Its name describes its resting pitch: acem ("Persian," a named pitch position in the perde system) plus aşiran ("lower register"), indicating the lower-octave form of the acem perde. The makam takes its karar on this pitch and unfolds a purely Pythagorean interval structure identical to Çârgâh — the same pattern as the Western F major scale. Yet Acemaşiran sounds nothing like its parent: where Çârgâh ascends from the karar, Acemaşiran opens from the upper register and descends, giving the same intervals an entirely different melodic identity.

Çeşni construction

Established Acemaşiran joins a Çârgâh beşlisi (pentachord) on the acemaşiran perde to a Çârgâh dörtlüsü (tetrachord) on çârgâh — the same building blocks as Çârgâh, relocated to a new starting pitch. The Çârgâh beşlisi's interval pattern is T T B T (9+9+4+9 commas = 31 commas); the Çârgâh dörtlüsü's is T T B (9+9+4 commas = 22 commas). Concatenated — 9-9-4-9-9-9-4 — the sequence sums to 53 commas, a full octave.

Established Because both çeşni are purely Pythagorean, using only tanini (whole tones) and bakiye (diatonic semitones), Acemaşiran contains no microtonal intervals. It is one of the few makams fully playable in 12-tone equal temperament — a trait it shares with its parent Çârgâh and its sibling şed Mahur.

Scale in Holdrian commas

Established The ascending scale, in commas above the karar (acemaşiran):

Established The ascending intervals in commas are: 9-9-4-9-9-9-4. These are the same intervals as Çârgâh and Mahur — a Pythagorean major scale — starting from the acemaşiran perde.

Functional pitches

Established Karar, güçlü, and yeden define Acemaşiran's melodic behavior:

• Karar (resting tone): Acemaşiran perde — where the piece concludes. This sits in the low register of the standard perde system, giving the makam a characteristically deep tonal foundation.
• Güçlü (primary center): Acem — the eighth degree, one octave above the karar. This high güçlü is characteristic of makams with a descending seyir: the melody gravitates around the upper register before descending to resolution. Compare Muhayyer, whose güçlü similarly sits at the upper octave.
• Yeden (leading tone): Hüseynî Aşiran — one tanini (9 commas) below the karar, pulling upward toward the acemaşiran perde in cadential motion. As in Hüseyni (whose yeden is also a whole tone below the karar), the leading-tone pull comes from a full step, not a semitone.

Attested Tanrıkorur (1988) lists çârgâh and dügâh as secondary emphasis pitches alongside the primary güçlü, serving as resting points that structure the melodic descent into distinct phrases.

Seyir: the melodic path

Attested Acemaşiran's seyir classification is a point of disagreement among sources. Signell classifies it as inici (descending), consistent with the güçlü's placement at the upper octave — the melody begins in the high register around the acem perde and descends through the scale to rest on the karar. Tanrıkorur's 1988 TDV İslâm Ansiklopedisi entry instead describes the seyir as çıkıcı (ascending).

Practice The inici classification aligns with the makam's structural features: the güçlü at the eighth degree, the parallel with Mahur (the other Çârgâh şed, also classified inici), and the broad melodic contour described by modern conservatory sources. This is the classification adopted here, though the discrepancy reflects genuine variability in how historical and modern sources categorize directional tendency.

Practice The broad shape:

1. Begin near the güçlü (acem perde), establishing the makam's identity in the upper register.
2. Introduce the Çârgâh dörtlüsü descending from the upper octave, with phrases pausing on çârgâh and dügâh as secondary emphasis points.
3. Descend through the Çârgâh beşlisi toward the karar, with phrases that may temporarily ascend back toward the güçlü region before the final resolution.
4. Conclude with a cadential phrase on the karar (acemaşiran), often approaching through the yeden (hüseynî aşiran) from below.

Transposition and identity

Established Acemaşiran is classified as a şed makam — a transposition of Çârgâh. The relationship is exact: every interval in Acemaşiran matches Çârgâh degree for degree. The only structural change is that the karar shifts from the çârgâh perde down to the acemaşiran perde, a distance of 22 commas.

Established The same parent produces a second şed: Mahur, which transposes the karar to the rast perde. All three share the interval pattern T-T-B-T-T-T-B, yet they are distinct makams because their seyir, güçlü placement, and repertoire differ fundamentally. Çârgâh ascends from the karar; Mahur and Acemaşiran descend from the upper register. Çârgâh has almost no classical repertoire; both şed forms have been in continuous use for centuries.

Practice This trio — Çârgâh, Mahur, and Acemaşiran — is one of the clearest demonstrations that transposition in the makam system creates genuinely different musical identities, not merely different pitch levels. The same intervals, the same construction, three distinct makams — because a makam is defined by its seyir, not by its scale.

Historical significance and repertoire

Attested Tanrıkorur (1988) characterizes Acemaşiran as one of the oldest and most frequently performed makams, with a history of approximately four and a half centuries. This places its documented use at least as far back as the sixteenth century, during the flourishing of Ottoman court music.

Attested Notable composers who wrote in Acemaşiran include Neyzen Salih Dede, Şeyh Hüseyin Fahreddin Dede, İsmail Dede Efendi, and Zekâi Dede — figures spanning the eighteenth and nineteenth centuries who represent the core of the Ottoman classical tradition. The twentieth-century composer Alaeddin Yavaşça continued the tradition with modern works in this makam.

Practice Despite sharing its interval structure with the Western F major scale, Acemaşiran's descending melodic character and its deep roots in Ottoman compositional practice give it an identity that no Western major-key piece would approximate. The makam's longevity — outliving countless theoretical frameworks and notation systems — speaks to the enduring musical logic of the Çârgâh intervals in this particular register and with this particular melodic approach.

Modulation

Attested Tanrıkorur notes that Acemaşiran commonly modulates toward Sabâ makamı. The transition is facilitated by the shared emphasis on the dügâh perde — Sabâ's karar — which already functions as a secondary resting point within Acemaşiran's descent.

Practice Other modulatory paths follow from the Çârgâh-family kinship. Phrases emphasizing the çârgâh perde (fifth degree) can open the door to brief Çârgâh-flavored passages, while dwelling on the rast perde (second degree) can suggest Mahur territory — a natural consequence of navigating through the same interval set at different pitch levels.
