![]() ![]() And an augmented 6th is a half step wider than a major 6th. Since C natural is "La" in Eb major, three flats. One more, what is an augmented 6th down from C#? First, C anything down a 6th is E something. Remember shrinking a perfect interval gives a diminished interval, not a minor one. And you know that raising the bottom note or lowering the top note shrinks the interval, making it narrower. You know that perfect 4ths have the same accidentals. How about D# to G natural? You know that D to G is a 4th. The major 3rd has been made wider so the interval is augmented. For example, what is the interval Ab up to C#? If you already know that A to C# is a major 3rd, you know that Ab to C is also a major 3rd and you can easily figure out Ab to C#. If you have memorized your major 3rds, even just the major 3rds up from the white keys on the piano, and if you remember that all perfect intervals have the same accidentals except for the two between B and F, you can figure out any unknown interval by comparing it to a known interval. Let's start this lecture by practicing labeling and spelling intervals. But there are faster ways, such as using scale degree relationships, Do up to any diatonic interval is major, or perfect. For example, a diminished 5th has 6 half steps. We saw how we can count half steps to figure out intervals. 2nds, 3rds, 6ths and 7ths can be Major, Minor, Diminished or Augmented. We said Unisons, 4ths, 5ths and Octaves can be Perfect, Diminshed and Augmented. To avoid this eventuality many users will use a small holster to carry the pipe.In the last lecture, we defined all the possible intervals. This usually requires disassembly of the pipe in order to clean the lint off the reed. Carried in a pocket, a pipe will occasionally pick up small bits of lint which works its way into the narrow space around a reed. Because of this, replacement reed plates are sold. The brass reeds in common pitchpipes are subject to work hardening with use, so they gradually change pitch. In Ethnomusicology, recording a short beep with pitch pipe in ethnographic recordings can be used in playback to determine the playback speed of the Gramophone record or Phonograph cylinder. Less frequently the pipe will be used to play the first sung note of the song, especially where the song begins in unison or with a solo. The singers' normal use of the pipe is to play the initial key note or tonic of the piece to be sung. Pipes in other keys are available, but are much more rare. However, it is particularly notable that the Men's pipe in F is pitched higher than the Women's C pipe. Most male and female performers prefer to use F-F pipes and C-C pipes, respectively. Different pipes are available for bass and treble voices due to variations in vocal range. By providing all of the notes of a single octave, a singer can start in any key called for in Western music. Chromatic pipes most often provide thirteen pitches, each a half step above the previous. Chromatic pitch pipes are favored by a cappella singers and timpanists. Some pitch pipes are intended for tuning string instruments, and only provide reeds for notes appropriate to a particular instrument. In recent years, electronic push-button devices simulating chromatic pitch pipes have become available which are small enough to fit on key chains. The airflow is modulated by the oscillating reed, then it resonates in an outer sounding chamber. ![]() Inside the pipe, the air flows through a hole in a plate past the selected rectangular metal reed (usually brass). These are discs with the holes for the reeds around the perimeter and with marked openings for each note, into which the user blows. The most common type is a circular free reed aerophone. They are also useful for establishing what pitch standard was being used at a particular place and time.Īlthough few look like a pipe, the pitch pipe name is still applied to any device used as a pitch reference. They are now quite rare, and hardly ever used for what they were intended, but may still be used as an alternative to a tuning fork. Pitch pipes of this sort were most often used in the 18th and 19th centuries in churches which had no organ to give the opening note of a hymn. Pitch pipes come in all sorts of shapes and sizes. On this plunger are marked the notes of either the chromatic scale or the diatonic scale, and by setting it to the correct position, the indicated note will be produced when the instrument is blown. The pipe was generally made of wood with a square bore, and the plunger was leather-coated. The earliest pitch pipes were instruments similar to the recorder, but rather than finger holes, they had a plunger like a slide whistle's (also known as a swanee whistle).
