Bedeutung der Verwendeten Symbole
K = Korrektur bei der zu errechnenden Instrumentenlänge
An der Anblasstelle:
KL = Labium-Korrektur der Blockflöten
KML = Mundloch-Korrektur der Traversflöte einschließlich der Auswirkung der Lippen, des Ansatzes
KMS = Mundstück-Korrektur des Schnabels mit einfachem Rohrblatt
KDR = Korrektur, hervorgerufen durch das Rohr (Doppelrohrblatt)
KMA = Kesselmundstück-Korrektur einschließlich der Auswirkung des Ansatzes
KSP = Spitzen-Korrektur, bei konischen Instrumenten die Ergänzung der fehlenden Konus-Spitze
KO = Korrektur wegen offener Tonlöcher
D = Durchmesser der Instrumentenbohrung
d = Durchmesser eines Seitenloches (Tonloch oder Mundloch)
w = Wandstärke
Epr = Endpunkt eines Tones, an dem man die vom praktischen Anfang gemessene Röhre abschneiden müsste, um diesen Ton zu erhalten.
Eth = Endpunkt vom theoretischen Anfang gemessen
EB = Unteres Ende des Schallstückes (am offenen Ende des Instrumentes) (gemessen vom praktischen Anfang des Instrumentes)
Am offenen Ende:

T = Periode = Dauer einer Schwingung
λ = Wellenlänge
cot = Cotangens (Winkelfunktion)
l = praktische Länge der Röhre
f = Frequenz = Schwingungszahl
c = Schallgeschwindigkeit
Δ = Tonhöhendifferenz (in Cent)
