Mega.co.nz, web-based file streaming & Copy.com users

The following is an open letter to Mega.co.nz about implementing web-based audio file streaming (and attracting Copy.com users):

March 31, 2016
To the management (and developers) of Mega.co.nz:

In two months, on May 1, 2016 (as you may know), Barracuda Networks will close its (reportedly) "highly rated" Copy.com service.

They are directing "millions of users" to convert to Microsoft's similar service.

Instead, to attract some of those users, it might be in Mega.co.nz's best interest to implement certain Copy.com features. I'm thinking of one in particular:

Copy.com's web-based file manager directly automatically streams audio files (particularly Ogg-Vorbis files: those with extension OGG; and MP3 files).

Thus, whenever users shared (with other people) a web link to a directory tree on Copy.com, then the recipients, simply by navigating there, could stream that audio immediately and directly.

In other words, the recipients of the link could find and stream (in a web browser) any audio file: this without any additional (bothersome or worrisome) steps required; i.e., to:
  1. Download the audio file;
  2. Choose an audio player program; or even
  3. Install a special audio player for Ogg-Vorbis files.
In many cases—for many recipients—these additional steps can be show-stoppers.

This is particularly true in the case of public links.

Many Copy.com users would find this direct-streaming feature highly useful, IMO.

Mega.co.nz could attract more Copy.com users to their service by duplicating this feature.

Does Mega.co.nz plan to add this functionality—of direct-streaming Ogg-Vorbis (extension .ogg) or MP3 files—to their web-based file manager? Would Mega.co.nz's management consider it?

Already, Mega.co.nz's phone apps stream audio. In the web-based file manager, a need for this exists also, for the easiest possible access when sharing web links.

With warm regards,

Thomas Young mass setting open letter

Subject: Thomas Young mass setting by Mark D. Blackwell

TYC Administrator
Thomas Young Centre

Dear madam:

Since your website:

http://www.thomasyoungcentre.org/about-tyc/contacts/

indicates you as the first point of contact, I write to announce with pleasure that I have composed a mass setting in honor of your own Thomas Young, the famous polymath.

This entire mass setting was inspired by Thomas Young's list of major thirds in his own Young Temperament (a well-temperament for keyboards). He arranged these thirds in order of increasing size (thus increasing distance from purity). In his design, this order matches the key signatures with increasing numbers of sharps and flats. His temperament (I assume you know) is described here:

http://en.wikipedia.org/w/index.php?title=Young_temperament&oldid=505261244

To be more explicit, the chord roots in this mass setting exactly follow Thomas Young's ordered sequence (or otherwise relate to it): C, G, F, D, Bb, A, Eb, E, Ab, B, Db, Gb.

You might find it amusing to inform your membership of this connection to your namesake, perhaps in a note in a publication. At least, I hope so!

The "Thomas Young" mass setting can be heard here (click the icons which depict two notes on a staff):

Compositions self-nominated to Baker Artist Awards

I nominated my musical compositions for consideration for the various local Baker artist awards and grants (of Baltimore) by adding a page on their site just now.

Please consider looking! As you know, comments are love (there, as ever).   :-)

Rare, select chamber music (sheet music and MP3)

Here are some rare, excellent, beautiful, intelligent and select chamber music pieces of famous and once-famous old composers, culled by listening carefully to the sound samples on Edition Silvertrust's website. They also publish The Chamber Music Journal. I audited their full catalog of sheet music in two categories: quite a number of pieces! (I developed the list for some of my acquaintances with whom I play music, and have clarified the titles, somewhat. Originally, it may have been a recommendation from Delicious.com which led me to Edition Silvertrust, but I am not sure.)

All the best, excellent pieces, and only the best ones, are on this list. This is only my educated opinion; and yet, I believe you should enjoy them if you heard them! But merely let me mention my extensive classical music background. I invite you to judge for yourself!

========================
String and clarinet quintets:

Joseph Eybler (1765-1846), String Quintet for Violin & 2 Violas (or 2 Violins & Viola), Cello & Bass in D Major, Op.6 No.1 (1801)

Friedrich Dotzauer (1783-1860), String Quintet for 2 Violins, Viola & 2 Cellos in d minor, Op.134 (1835)

This one is operatic:
Luigi Cherubini (1760-1842), String Quintet for 2 Violins, Viola & 2 Cellos in e minor (1837)

Johan Svendsen (1840-1911), String Quintet in C Major, Op.5 (1867)

Charles Villiers Stanford (1852-1924), String Quintet No.1 in F Major, Op.85 (1903)

Alexander Krein (1883-1951), Three Sketches on Hebrew Themes for Clarinet Quintet Op.12 (1914)

========================
Piano quintets:

Camille Saint-Saëns (1835-1921), Piano Quintet in A Major, Op.14 (1853)

Elfrida Andrée (1841-1929), Piano Quintet in e minor (1865)

Giovanni Sgambati (1841-1914), Piano Quintet No.1 in f minor, Op.4 (1866)

Friedrich Kiel (1821-1885), Piano Quintet No.1 in A Major, Op.75 (1873-4)

Hermann Goetz (1840-1876), Quintet for Violin, Viola, Cello, Bass & Piano in c minor, Op.16 (1874)

Carl Frühling (1868-1937), Piano Quintet in f sharp minor, Op.30 (1894)

Salomon Jadassohn (1831-1902), Piano Quintet No.3 in g minor, Op.126 (1895)

Ermanno Wolf-Ferrari (1876-1948), Piano Quintet in D flat Major, Op.6 (1900)

Wilhelm Berger (1861-1911), Piano Quintet in f minor, Op.95 (1904)

Théodore Dubois (1837-1924), Quintet for Oboe (or Clarinet or Violin), Violin, Viola, Cello & Piano in F Major (1904-5)

Sergei Taneyev (1856-1915), Piano Quintet in g minor, Op.30 (1910-11)

========================
Piano sextets:

This one is not hard for piano (unlike the usual Glinka), because he intended his Italian doctor's daughter to play it:
Mikhail Glinka (1804-57), Grand Sextet for Piano, String Quartet & Bass in E flat Major (1832)

William Sterndale Bennett (1816-1875), Sextet for Cello & Bass (or 2 Cellos), 2 Violins, Viola & Piano in f# minor, Op.8 (1838)

This one has fewer notes than usual for strings:
Ludwig Thuille (1861-1907), Sextet for Flute, Oboe, Clarinet, Horn, Bassoon & Piano in B flat Major, Op.6 (1888)

Paul Juon (1872-1940), Divertimento (Piano Sextet) for Flute, Oboe, Clarinet, Horn, Bassoon & Piano, Op.51 (1913)

MP3 bit rates for various occasions

After carefully listening for a couple of days to MP3's made from a WAV file recording of a brass, choir and organ rehearsal, I developed some rules of thumb about bit rates. I concluded the following minimums are indistinguishable from WAV files in capturing the music of their various types. They are expressed in the usual thousands of bits per second, Kbps:

Speech (without too many resulting artifacts) needs 56.
(Hymns with) descant need 64.
Brass instruments reduce the needed rate for choirs to 64.
Choir a capella (they are rather pure tones, or maybe it is the harmony) needs 80.
A single cantor (alto) needs 128.
Propers (increased because the choir response pitches are slightly clustered) need 160.
Hymns (depending on the organ stops) need 64 to 192.
Organ (because of reed and string stops) needs 192.

(The tests were done using Audacity v. 1.2.6 and MP3 LAME v. 3.98.)

BTW, Apple's iTunes Store uses 128-Kbps AAC (Advanced Audio Coding) format, claiming equivalence to 160-Kbps MP3.

Edited April, 2012 to include AAC.
