    1. street bands, made up of various combinations of brass instruments, clarinets, and drums, which played marches, hymns, popular songs

      open-air performances - needed loud instruments

    1. To answer your question about register, register doesbelong to the domain of timbre but differs from instrumentation that also belongs to timbre. I understand that in organ music the word "register" is synonymous to characteristic timbres of musical instruments. But confusion like this is inevitable with any of the 11 aspects: "melody" can have its own "harmony" (e.g., solo flute sonatas by CPE Bach), rhythm can be "metric" (e.g., compositions written in the genre of "perpetum mobile", e.g., Paganini or Weber), articulation can be dynamic (e.g., accent), etc..

      The distinction between register and instrumentation is that register is bound to pitch and underlies instrumentation. Every instrument and vocal usually breaks into 3 registers that can be classified in 2 general types: intensity growing towards the top (vocals and brass) or 5towards the bottom (reed woodwinds and strings). This typology goes against and across the distinctions between different timbres of the instruments. However, the distinctions between registers can be greatly reduced. For instance, the bel canto training can completely conceal a breaking point between neighboring registers. Also, the timbral differences between different instruments (and vocals) greatly exceed the timbral differences between different registers of the same instrument (or voice type).Yet another important distinction is that register plays a formative role for tonal organization of modes of timbre-oriented music that are characterized by indefinite pitch (relative and variable pitch values), such as ekmelic and khasmatonal modes. In such modes, the degrees are defined in regards to their position within a vocal register(s). It is possible that the same principles are in play in the instrumental forms of music of the same ethnicities that keep cultivating such vocal music (e.g., music for Jaw Harp or musical bow). The aspect of instrumentation completely misses this formative melodic modal function. Combinations of timbral colors of different instruments do notform specific musical modes. Timbral coloration is known to be modally formative only in instrumental ensembles consisting of the sameinstrumental types -e.g., a set of gongs. But then, such cases fall within the domain of register rather than instrumentation.On the other hand, instrumental timbres often blend, forming new composite colors (for example, clarinet + oboe). There is nothing remotely similar in the domain of register -registers don't blend.It can be generalized that register fundamentally opposes instrumentation: register is based on timbral similarity, whereas instrumentation -on timbral contrasts. Composers select a specific instrument to "color" constituent sounds in a musical composition in different colors. Singers (and possibly instrumental players) usually select a specific register to secure unityin timbral coloration for the pitch-classes of a musical mode. Timbral contrasts are important in khasmatonal music, where a mode is defined by the group of pitch classes of one register contrasting the other register (e.g., falsetto or rasping). However, such music is rather rare and is still operated by the principle of integratingtimbral colors into a melodic phrase rather than by differentiation of timbral color to color the music textures, as it occurs in instrumentation. The only exception is Schoenberg's experiments with Klangfarbenmelodie that did not work -and could not work, because changes of instrumental timbres within the same melodic stream has been demonstrated to segregate this stream into fragments that obstruct phrasing.

    1. SOUND SUPPORT PHRASINGThe last performance directive to cover is quite important, and one that is often overlooked~ that of sound support phrasing ~ the direction as when to start and when to stop produc-ing a sound irrelative to pitch change.Whether the sound is produced by blowing, plucking, scrapping or hitting, there is a pointwhen the performer needs to take a breath, raise the arm, or move the bow toa starting posi-tion; all affect the phrase qualicy ofa melody. There are two considerations the composermust make; (1) how long the sound production can last depending on the tempo of theperformance and the abilities of the performer, and (2) how will the pause ro take a breathor raise a bow affect the phrasing of the melody. Careful preplanning is required to assure asuccessful interpretation of your melody.

    1. One common use case for rbspy is profiling slow unit test runs -- instead of spending a bunch of time adding instrumentation, you can run rbspy record ruby my-test.rb and instantly get profiling information about what's going on.

    1. Arguments for “it depends.”

      Exploratory research - descriptive -- light instrumentation Confirmatory study - use well structured Multiple case - standardization will help to cross compare.

      See Figure 2.7

    2. rguments for a lot of prior instrumentation.

      If research specificity exists, prep accordingly Focused interview schedules keep focus tight Comparative case studies? Use the same instrumentation (helps build theory) Validated instruments keep researcher bias out.

    3. how you will get that information.

      The discussion on instrumentation begins here: - A device for recording and observing that can be reconfigured. Notes or not, recording or not? Recordings listened to or not? Transcribed or not? How to write up notes?

    1. public void increment(String label, String topic) { + Stats.incr(label); + }

      import io.prometheus.client.Counter; public static final Counter requests = Counter.build() .name("requests_total").help("Total requests.").register();

      public void increment(String label, String topic) { requests.inc(); // Your code here. } }

    2. The component is pluggable, you can configure ingestion of metrics to any monitoring system by implementing MetricCollector interface. By default metrics are sent to Ostrich, statistic library bundled into secor.

      Just inject prometheus simple client into this module and you could get prometheus working for secor.
