F1 is also known as “contra F” or “double pedal F. Names of the C-Notes: C0: triple pedal C C1: double pedal C C2: pedal C C3: bass C C4: middle C C5: treble C C6: top C or high C C7: double top C or double high C C8: triple top C or triple high CĪll of the notes may be called out using these systems.Octave Names (pictured above): C0 - B0: sub-contra octave ( A0 is the lowest pitch on a full piano) C1 - B1: contra octave C2 - B2: great octave C3 - B3: small octave C4 - B4: one-line octave, or 2nd small octave (contains both middle C and A440) C5 - B5: two-line octave, or 3rd small octave C6 - B6: three-line octave, or 4th small octave C7 - B7: four-line octave, or 5th small octave C8 - B8: five-line octave, or 6th small octave ( C8 is the highest pitch on a full piano).Each octave, as well as each C, has its own universal name. In pitch notation, the notes C4, D4, and B4 belong to the same pitch class, which is the fourth octave.īut, pitch notation is just one way of referencing notes. Pitch class simply refers to an octave from one C to the next. This means if you play a C note through an octave pedal, you will still hear a C, but it will be an octave higher or in some cases. When I have been playing for about 15mins or so I find that I can keep the low notes at the correct octave more easily but my teacher says that I should be able to (or the Sax should) get. This is the distance between, for example, one C note and the next C note. The problem I am having is that when I play the lower notes D, E, F (mainly) it easily jumps to the higher octave note, especially at the start of practice. Unless both are present, you do not have the full designation of a specific pitch.Each octave begins on C so C3 is in the third or “small octave,” and C4 is in the fourth or “one-line octave.”. A guitar octave pedal is designed to allow you to shift your guitar’s sound eight notes, or twelve semitones (12 frets on a guitar). Note that a complete designation contains both the pitch-class name (a letter name plus an optional sharp or flat) and the register (the ISO number indicating the octave in which the pitch is found). Thus a half step below C4 is C-flat4 (even though it sounds the same as B3), and a half step above C4 is C-sharp4. Pitches on the tenor staff are as follows:Īny accidentals follow the octave designation of the natural pitch with the same generic name. Pitches on the alto staff are as follows: So an ascending scale from middle C contains the following pitch designations:Īnd a descending scale from middle C contains the following pitch designations: The tricky bit about this system is that the octave starts on C and ends on B. sound is produced when two notes separated by one octave are played. An octave higher than middle C is C5, and an octave lower than middle C is C3. The A5 key is thus one octave higher than A4. In that system, middle C (the first ledger line above the bass staff or the first ledger line below the treble staff) is C4. We will follow the International Standards Organization (ISO) system for register designations. A pitch-class plus a register together designate a specific pitch. In fact, if all you have is C-sharp or B-flat, you do not have a pitch, you have a pitch-class. When specifying a particular pitch precisely, we also need to know the register. Theoretically, each key could have several names (the note C could also be considered D♭♭, for instance), but it’s usually not necessary to know more than two enharmonic spellings. In air at normal atmosphere and 0 o C the speed of sound is 331.2 m/s. wavelength (m) c speed of sound (m/s) f frequency (s-1, Hz) Example - the Wavelength of a Tone. Frequency can also go in fifths by using the. To find the frequency of a note one octave lower the frequency is halved. To find the frequency of a note an octave higher the frequency is doubled. When two pitch classes share a key on the keyboard, they are said to have enharmonic equivalence. The wavelength of sound is the distance between the analogous points of two successive waves. 'Playing middle C on the piano keyboard produces a sound with a frequency of 256 Hz.' 256 Hz: Intervals. Middle G is 7 semitones above middle C, so its specified by the number 7. Notice that some of the keys have two names. Press the play button to actually play sounds. On the illustration below, the pitch-class letter names are written on the keyboard. The keyboard is great for helping you develop a visual, aural, and tactile understanding of music theory.
