The Mahler Hammer at Eastman

The Eastman Philharmonia under Neil Varon’s baton performed Mahler’s 6th Symphony on 14Nov2018. In need of a Mahler Hammer (on short notice) Neil contacted me about either renting, buying, or having one made. Since the hammer detailed on this site was available from the Duke University Wind Symphony I worked with the Eastman School staff to have it shipped to them in time for their last rehearsals and performance.

Good striking form!

Mahler Hammers can also be used for “percussive maintenance”!

 

 

 

Just in case you thought . . .

. . . my previous post was useless, here’s something to consider.

You go to a nice restaurant and order a $40 glass of Domaine de Montille Corton Clos du Roi Grand. The sommelier pours you a bit, you swirl, smell, sip and nod your approval. The sommelier pours your wine and leaves you looking at the glass wondering if you’ve been cheated.

The shape of the glass is determined by the function sin(x). Here’s the plot (x=0.0 to 1.5 radians) from the R statistical system. It’s been rotated 90 degrees counter clockwise to make visualization easier and is marked at x=0.75 (half the height) and x=1.111871 (half-full by volume).

Using this as a template draw a cross-section of a nice wine glass and fill it to half the height (fig. 1) and half the volume (fig. 2) like so:

Being a beer kind of guy, if I’m going to spend $40 on a glass of wine, I want a full glass of wine. But, as you can see what appears to be a fairly full glass of wine is still only half full by volume. To prove this we can use the program from the previous post to calculate the volumes bounded by a = 0.0 and b = 1.111871 and a = 1.111871 and b=1.5. Here are the results:

[Walters-iMac:~/desktop] wemrt% python halffull.py
lower_bound = 0.000000
upper_bound = 1.500000
height      = 1.500000
volume      = 2.245359
half-volume = 1.122680 <- This should be the volume of the
                          top half of the glass.

Tolerance : 0.000001
Iterations: 20
lower_bound = 0.000000
upper_bound = 1.111871
height      = 1.111871
volume      = 1.122679

Then using the upper_bound for the lower_bound and 1.5 for the upper bound:

[Walters-iMac:~/desktop] wemrt% python halffull.py
lower_bound = 1.111871
upper_bound = 1.500000
height      = 0.388129
volume      = 1.122676 <- Off by 4 X 10^-6 rounding error.
half-volume = 0.561338

Tolerance : 0.000001
Iterations: 19
lower_bound = 1.111871
upper_bound = 1.315996
height      = 0.204125
volume      = 0.561337

So, yes you we’re being shorted by quite a lot of wine. Call the sommelier back, show him this post and tell him that for $40 he can bloody well give you half a glass of wine.

 

NCSE/UNC Spectrum Concert

The North Carolina Saxophone Ensemble and the UNC Saxophone Studio will perform on 11Apr2014 in the Kenan Music building rehearsal hall. The program notes for the concert will be projected on a large screen rather than printed, saving paper and allowing people to review the program both before and after the performance. To see the program notes click here.

Here are short descriptions of each piece.

Four5 – The fifth in a series of pieces for four players by John Cage. Cage wrote the “Number Pieces” later in his career. Click here for more information.

Melodies for Saxophone – Thirteen melodies written by Philip Glass for Jean Genet’s play “Prisoner Of Love” adapted by Joanne Akalaitis for the New York Theater Workshop.

The Difficulties – Electronica by Mark Engebretson and poetry by Brian Lampkin. For this performance a jazz baritone saxophone improvisation triggers electronic sounds to compliment the reading of Lampkin’s poem “The Difficulties”.

Far Away – Takatsugu Muramatsu is most noted for his work in film and television but “Far Away” was originally written for the Libera boys choir.

Last Tango in Bayreuth – Peter Schickele originally played this on piano as something of a party trick, eventually completing it as a quartet for four bassoons. It’s a tongue-in cheek tribute to Richard Wagner based on the “Tristan” chord from Tristan ind Isolde and a theme from “Overture to Act III” of Loehengrin.

Shetland Sequence – An arrangement of Shetland jigs by the British saxophonist Jan Steele. The jigs included are “Jack broke da prison door”, “Donald Blue”, “Sleep sound ida morning'”, “Lassies trust in providence”, and “Bonnie Isle o’Whaljay”.

Ecstatic Fanfare – An arrangement of the brass fanfare from the first movement of Steven Bryant’s “Ecstatic Waters” for wind ensemble.

Smiles and Chuckles / Beautiful Ohio Blues – These two pieces date from the early 20th century and were written for the Columbia Saxophone Sextet and The Six Brown Brothers. The arranger, David Lovrien, transcribed the pieces from recordings made on wax cylinders making these truly authentic saxophone pieces.

Capriol Suite – A collection of six dances with a Renaissance flavor written in 1926 by Peter Warlock. Originally written as a piano duet, Warlock re-scored the work for orchestra.

Festive Overture, Opus 96 –  Dmitri Shostakovich wrote this work in three days for the 37th anniversary of the October Revolution in 1954. Stylistically it is based on Glinka‘s Russlan and Ludmilla overture written in 1842.

Trilogy – A transcription of the opening vocal section of the larger work of the same name by Keith Emerson and Greg Lake with the tenor sax taking the vocal solo and the ensemble covering the piano parts.
